DIY AR-15 Build: Introduction, Parts and Tools Required

By The ITS Crew

1 of 8 in the series DIY AR-15 Build

Today marks the start of a new series on ITS Tactical where we’ll be walking you through the COMPLETE assembly of a Direct Gas Impingement AR-15. There’s an awesome offer involved with this build too, so be sure to read on below to find out what’s in store!

We’ll be starting this journey with an introduction to the series where we’ll go over the laws surrounding owning and building your own AR, as well as the parts we’ll be using and the tools required. Up front you should know that building your own AR-15 isn’t as hard as you think and there’s not better way to learn about the AR platform than to build one from the ground up!

Rather than go over an assembly of a standard AR, we’ve included what we feel to be some of the best and cost effective hard-working aftermarket parts to consider when building your own AR. This series is also a supplement to our articles on How to Keep Your AR Running. We decided to undertake this new build series so we’d have details to refer to when we discuss in the common wear parts and replacement schedules.

Special Offer

Before we get into the build and laws, we’d like to mention a special offer for ITS Tactical Plank Owners and Crew Leaders ONLY. We’ve partnered with Spike’s Tactical to put together a special run of stripped lowers with the same ITS Tactical Logo Laser Engraving seen in this photo.

stripped lowers

The stripped lowers will run $99.00 plus a $5.00 engraving fee. Spike’s will be handling the payment and we’re not making any profit on these, we’re doing it as a thank you to our supporting members! As this is a members only purchase, please click here for all the details on how you can reserve your ITS Tactical engraved lower!

These are very much a limited edition and won’t be available for long!

AR-15 Laws and Restrictions

AR-15 laws and restrictions

The very first and most important thing we’re going to mention is to always KNOW YOUR LOCAL STATE LAW! While we’ll go into some specifics regarding laws and restrictions, you should always defer to your state law. Federal law has NO RESTRICTIONS preventing you from owning an AR-15!

We’d suggest familiarizing yourself with the past Federal Assault Weapons Ban and what life used to be like back in late 1994 thru 2004 and how the government stepped in with restrictions on so called “assault weapons.” While there have been attempts to revive these restrictions, nothing has even reached the House floor.

There are however, quite a few state restrictions on owning an AR-15 in California as well as other state restrictions on things like stocks and flash hiders/suppressors. It’s depressing to even talk about them and perhaps we’ll address those at some point, but for the sake of brevity, just move out of California.

Under federal law, the Lower Receiver is the only serialized part on the AR-15 and the only part that is considered a firearm. This means that the ATF requires the buyer has a Federal Firearms License or uses a licensed FFL dealer to conduct the transfer of the Lower Receiver from manufacturer/distributor to buyer.

Form 4473 will need to be filled out and most FFLs will take care of this transfer for you by charging a fee, commonly refered to as a “transfer fee.” This can range from $25 to $75 depending on the dealer. It never hurts to call around to your local dealers and find out if they deal with FFL transfers and what they charge for transfer fees. Just always use a reputable dealer!

An exception to this is if you’re buying a lower or firearm from a private individual who isn’t a licensed dealer, in this case you DO NOT have to fill out a Form 4473.

Short Barreled Rifles

shooting the ar-15

Now that you understand the federal laws surrounding the lower, you’re probably wondering about barrel length and aftermarket parts. The National Firearms Act classifies any AR-15 having a barrel length under 16″ or an overall length under 26″ (with any collapsible stock extended) as an SBR (short barreled rifle) and listed as an NFA firearm.

So basically you have to have a minimum 16″ barrel or a minimum overall length of 26″ with a collapsible stock extended. You can however have a 14.5″ barrel with a permanently attached flash hider/compensator that brings the 14.5″ barrel up to the minimum length of 16″. That’s what we’ll be doing in this series.

As the lower is the only serialized part, you can technically purchase any size barrel, complete upper or any part for that matter without any worry about federal law. Pay attention to this next part though, because as soon as you assemble the firearm using those parts you’re subject to federal restrictions under the National Firearms Act.

We’re not going to get into the intricacies of owning an SBR in this article and will save that for a future article, but it’s definitely not illegal by any means. You just have to fill out a Form 1 to register a dedicated lower as your SBR and write the BATFE a check for $200 to buy a tax stamp. There’s of course a little more than that to it and since the lower is what’s registered as an SBR, you could have multiple uppers/barrels of different lengths that you swap out on that lower and still be in NFA compliance.

It’s your responsibility to know your state laws on ownership, not ours or the dealer/distributor selling you the parts, so do your homework!

What We’re Building!

DIY AR-15 Parts

We’re assembling a 14.5″ Direct Gas Impingement Hybrid AR-15. It’s a hybrid as it uses parts from various manufacturers and represents what we feel to be some of the most reliable and well made parts available on the market today.

AR-15 Parts

Lower Receiver

Upper Receiver

CRC Hydrographics

grip-tec

We were interested in getting all our Magpul accessories coated while assembling this build, as we’ve had an interest in the durability of water transfer imaging and how it holds up compared to Krylon. We reached out to CRC Hydrographics and are very fortunate we chose them for our needs, as they’ve just released an additional service they call “Grip-Tec.”

Grip-Tec ads an additional flat protective coating on top of the water transfer, which is nicely rubberized! It’s hard to show photos or video of the Grip-Tec at work, but from what we can say about our feedback so far is awesome! It really seems like a fantastic addition to their dipped patterns. Some intial feedback they’ve gotten so far is that it works well both combined with gloves and without.

It’s also important to note that the Grip-Tec is for use on firearm contact points such as stocks, grips, rail covers and handguards, etc. CRC notes that it’s also been popular on bolt action rifle stocks. We’re thoroughly impressed with the quality of the water transfer imaging and are looking forward to getting this build completed and putting it to the test.

Gunsmith Tools

ar-15 tools

It’s entirely possible to put together a complete AR-15 with not much more than a set of punches, but why wouldn’t you want to have the right tools for the job? We’re going to suggest a few tools that will make your life easier when assembling your AR and save you the aggravation of things like bent roll pins.

The reason this is so important, particularly with the lower assembly, is that the first purchase you’ll need to make after the Lower Receiver is a Lower Parts Kit. The LPK will come with just enough parts to assemble your lower. If you bend a roll pin or lose a part, you’ll either have to find a supplier that sells that part individually, or buy another LPK. Since we’re talking about LPKs, we’ll mention that we’re going to be using a Stag Arms Lower Parts Kit that comes with one extra Takedown Pin Detent. If you don’t know why that’s awesome, you will when we get to the assembly of the Takedown Pins.

As we’ll be starting with the assembly of a stripped Lower Receiver, we’re going to go over the tools that we’ll be using for the lower only. The tools for the Upper Receiver assembly will be discussed in the first article of the start of that assembly. These tools discussed are also not necessarily the minimum you can “get by” with. Our hope is that you approach wanting to learn how to assemble ARs as a way to learn about them, maintain them and keep them running yourself. With that, it’s important to have good tools at your disposal.

Workbench, Vise and Block

workbench, vice and block

The first thing you’re going to need is a good surface to work on. There’s lots of small parts to keep track of in a Lower Parts Kit and a large stable surface is highly recommended. At the same time you’re also going to need a sturdy vise to work from. The reason to have a vise is to securely hold an AR-15 Vise Block that’s used to place the magazine well of your lower on to work on it.

Punches

drive pin punches

While it’s perfectly acceptable to invest in a set of good steel Drive Pin Punches like this set from Starrett. While these are some of the best punches you can get, they have their limitations when it comes to working on the AR platform. AR-15s are assembled with many Roll Pins than can easily bend or cause your punch to jump off if you don’t strike them perfectly with a standard punch.

What we recommend is what you’ll be seeing us use, which is a set of Roll Pin Punches and Roll Pin Holders from Brownells. These are superior to standard punches, as the Roll Pin Holders do exactly what they sound like. They feature a hollowed out tip that holds the first 1/3 of a roll pin in an aligned position while you’re starting to tap it in. Once the roll pin has been properly started, you can then come back with the Roll Pin Punches to finish the job.

roll pin punches

The benefit of the dedicated Roll Pin Punches is the nipple on the face of each of these that automatically centers the punch and prevents the roll pin from collapsing. This can be especially important if you have to remove a roll pin for any reason, as damage will require replacement of the roll pin. Plus you can damage the surrounding metal.

Another tool we’d highly, highly, recommend is the Bolt Catch Pin Punch which is contoured to ride over the raised portion of the magazine well and drive the Bolt Catch Roll Pin straight and without damaging the surrounding metal.

One last tool is optional depending on how secure you’ll want your Castle Nut that holds on your Receiver Extension Tube (Buffer Tube). We’re jumping a bit ahead, but to properly “stake” the Castle Nut to prevent it from rotating you can either rely on the proper torque, use Blue Loctite (non-permanent) or stake it with a center punch. We’d recommend the Starrett 264E Center Punch or any well made center punch. You don’t need a spring loaded center punch unless you’re buying one to keep in your car in case you accidentally drive into a lake.

Wrenches and Hammers

wrenches and hammers

Since we just left off with the Castle Nut, you’re going to absolutely need a Stock Wrench to tighten the Castle Nut. We like the one we’ve linked to here, as it grips the Castle Nut in three places and has a cutout for inserting a torque wrench if you want to torque the Castle Nut to it’s proper spec of 40 in. lbs. If you do that, you’ll of course need the proper torque wrench too. As mentioned previously there’s other options though, rather than buying an expensive torque wrench. Totally your call though.

You’ll also need a lightweight Ball Peen Hammer (4 oz.) and a Nylon/Brass Hammer or a hammer that won’t mar metal. A set of Hex Wrenches would also be a good investment if you don’t already have a set. We’ll be using a 3/16″ Hex Wrench for the assembly of the Pivot Pin, but we show that to demonstrate how much of a pain it is to install the detent and assemble it so you’ll see why we suggest that you purchase the Brownells Pivot Pin Detent Installation Tool. It’s worth the price to prevent the headaches that come with your detent shooting across the room and crawling around on your hands and knees to find it.

Other Tools and Options

other ar-15 tools and options

If you elect to not purchase the Pivot Pin Detent Install Tool, you need a Multi-Tool or pair of needle nose pliers to hold the detent while you work your magic to get it installed. You’ll also need at least a 3″ long large flat head screwdriver to install the Pistol Grip Screw. Additionally a small diameter non-marring punch or something similar like a Takedown Tool is needed to depress the Magazine Release Button far enough in to properly install the Magazine Catch.

Again, keep in mind that these are just the tools needed for the Lower Receiver, some are needed again when working with the Upper Receiver, but those tools will be gone over later in the series when we complete the Lower Receiver assembly.

Notes

Now that you know what parts we’ll be building our AR-15 with and what tools we’ll use to assemble it, stay tuned for our next article where we’ll start the build with assembling the Lower Receiver. Specifically the next article will deal with installing the Magazine Catch.

Discussion

  • Dave J.

    Very cool.

    For the lowers I would be interested in a billet engraved one with the ITS logo. Similar to the Magpul or ARFCOM ones.

  • Having seen the Spikes lower and CRC Hydrographics parts in person I can tell you they both look killer. The feel of the Hydrographics parts is really awesome.

    Oh yeah, do yourself and your wallet a favor and buy a vice block and don’t try anything else,, ask me how I know.

    • awc

      ok, I’ll bite. How do you know?

    • I had a sneak preview at the ITS grand opening party. Had to keep it under wraps until now.

    • slag

      Well since I have both, I’ve never had need to block my vices; women, alcohol, smoking etc.

      But I do have to agree with the advice in the article with proper tools for the job @ hand, a vise block will definitely keep from twisting or crushing your receiver!

    • LOL good stuff!

  • Maverick9110e

    Awesome guys! I’ll be building and finishing mine in June so this will definitely come in handy!!

  • Adam B

    I built an AR, and I don’t think I used any special tools other than the castle nut wrench.

    I did get an already completed upper, but I didn’t use any punches or detent pin holders. I guess I got lucky with the detent pins.

    My secret weapon: MAGPUL MIAD Grip with integrated trigger guard. No roll pin needed.

  • Fastlane

    I just built my first AR about a month ago. Best project I’ve ever undertaken. Went in with zero understanding of the platform, but I managed to keep it under budget AND didn’t botch things up during assembly. Murphy must have taken a few days off.

    I ended up buying a Spike’s stripped lower, Del-Ton LPK, UTG collapsible stock and buffer assembly, and an R Guns complete upper (to avoid headspacing concerns). Picked up a Magpul rear MBUS and trigger guard shortly after I got everything put together. At the end of the day, factoring in the transfer fee and shipping, it ran me just over $650.

    Two hundred rounds and a reflex sight later, and the AR platform has officially become my favorite weapon system. This rifle in particular is not one I’d stake my life on, but it was intended to be a learning experience more than anything else. I’m sure this was the first build of many.

    Looking forward to the rest of the series.

    • Enzo

      So why wouldn’t you stake you life on it? If you built it properly there’s nothing a manufacturer would do that you didn’t. If you wouldn’t stake your life on it, throw it away.

    • Jason W

      Hey Fastlane,

      Very interested about your AR-15 build for $650. I’ve been trying to get started on one and have barely found any Lowers for that amount. I’d like to know where you went to purchase parts, best parts to look for, etc. 🙂

  • Jason

    The link to “Battle Comp 1.5 Compensator” isn’t working.

    • Thanks Jason, let us look into it.

      Looks like the site is being upgraded or is down

  • Kris

    What is the approximate total cost for parts and tools if we were to build the exact AR that is being described in this series. How will these parts compare to some of the higher end manufactured AR’s available for purchase today? This article has piqued my interested because I just started contemplating upgrading my AR to a newer (mine is a pre-ban), lighter version.

    • Quickly browsing over the article, it looks as if they used the parts many would consider “high end.”
      Id say this gun would easliy claim one of the higher end prices if it was bought as is.

      Just sent my e-mail out to you all, can’t wait to start a shorty build with the new lower!

    • Kris

      According to the links provided above, the prices (as of today) for all the parts listed above is approximately $1500.00 US. That does not count shipping and includes some parts that are on sale. That does not include any of the tools listed.

    • So far I have purchased all of the parts for the Lower Receiver as this is what I will build first and the total cost including taxes and shipping along with the FFL transfer for the receiver is: $525.11

      this does not include the cost to hydro dip the magpul parts as this will be an extra, im thinking somewhere around $300 for the entire rifle based on a few quotes i have gotten…

      also, many of the parts are on back order and apparently i will be waiting months for the parts i have orderd… im not complaining as i am very excited to get this project underway… im just letting you know…

    • Gary Brock

      Believe it or not, but I have GREAT success with finding back ordered parts on eBay or Amazon.com. Use judgment, of course. I don’t recommend buying a barrel from some guy on eBay. But, a lot of the other basic parts can be found on Amazon or eBay.

  • Pingback: DIY AR Building - INGunOwners()

  • Well I’ve been ordering parts to build an SBR in 300 Blackout when I get home and it looks like I just found my lower. Plus these articles will be great for brushing up, it’s been 2 years since the last time I built an AR.

  • BAND-AID

    Bryan I sent you a PM on the forum regarding a few questions. I am very interested.

  • It’s really not THAT bad in California regarding AR’s. I’ve got two very “evil” AR’s (and a third lower sitting anxiously), and the only thing different about them is I have to use a bullet button and a “tool” to remove my 10 round magazines.

    • Jay

      10 rounds, and a special button to reload? Hope your good at finding cover just my .02.

    • I don’t consider either of them my “defense” weapon. One is a dedicated coyote rifle, and the other was simply my first AR build. However, I do agree with you if I were to consider either of them my go to defensive weapon.

    • Phil

      Not that I’m advocating breaking any of CA’s ridiculous gun laws but there are ways around them. The easiest to get around is probably the 10rd mag, if you live in SoCal it’s easy enough to make a Vegas run and buy mags (in cash or through a friend) at one of their gun stores and bring them home. But if you were to use them in a home defense situation it might cause some problems but aside from a zombie apocalypse, I don’t really think that 10 round mags would be that much of a liability in home defense situation.

      As for the “bullet button”, there are companies that make “bullet buttons” that are designed to be easily removed or made toolless for if you were to ever to move to a state with more realistic gun laws.

  • Phil

    One very helpful thing to add to this article would be a list of tools needed or recommended. This way all a reader has to do is copy/paste the list into a Word file or something like that and can print it out or refer to while shopping online, that would be much easier than trying to sort through the article looking for all of the tool mentions.

    • Because we care 🙂

      Lower Receiver recommended tools:

      Workbench, Vise and Block:
      AR-15 Vise Block

      Punches:
      Standard punch set
      Roll Pin Punches

      Nylon/Brass Hammer
      Brownells Pivot Pin Detent Installation Tool

      Other Tools and Options:
      Multi-Tool
      Takedown Tool

    • I could (and should) write a blog on all the uses for blue loctite #242.

    • Jim Merit

      Fascinating. I cannot find a weapon that I can afford and my wife asks me every day how we are going to defend our family (3 kids).

      We have been impoverished by Obama and we cannot afford the 1-2 K Ars in gun stores.

      How much does it cost to join your organization?

      How much would the parts and tools cost for putting this AR-15 together?

    • Bob Smith

      You are really pathetic. You are impoverished by Obama? Maybe you are impoverished because you have a high school education and three kids to support. You sound like one of those people that absolutely hates “Obamacare” but would be the first in line for a free doctor visit since you are impoverished…I am by no means an Obama supporter but don’t BS a bunch of grown men. Is it really the president of the United States fault that “you” specifically are impoverished? Does Obama just make every decision for every corporation in America? I never knew the president could just make laws on his own with the approval of congress(the republican congresss) Why don’t you blame the owner of your local McDonalds franchise for letting you go in favor of some high school kid that doesn’t spout off stupid shit all day about how he can only qualify to work at McDonalds because of Obama.

  • what is the difference between a receiver with M4 feedramps and one without? basically, what the hell are M4 Feedramps? im building one with a 16inch barrel..what one do i need?

  • Cervantes

    I was a small arms repairer back in my Devil Dog days.
    This should be an easy build for me.
    I was about to drop $250 on an AK kit (me not know AK anatomy and stuff), but I think I’ll go American and build me an AR. I just had a question on making my AR accept 7.62. I’m sure it’s in the article, but I got places to go and things to do…Any problem w/ that change?
    I can’t wait to get started.

    • Exo

      Still kinda new to ARs also but I’m pretty sure all you need is swap out for a 7.62 barrel and magazine, everything else should be the same.

    • Chuck

      The bolt, too.

  • Matthew Bauer

    Can’t wait to see the rest of the series. I am following along with this to build my first AR although I went with a Daniel Defense LPK that comes with the Magpul Trigger Guard already. and will probably make a few tweaks along the way.

  • DugasM

    I was curious as to why you went with the impingment system instead of piston?

    • Dugas, We went with the impingement system because that’s what is more readily available and most piston guns are being bought “off the shelf” and not built. Not to say piston parts aren’t available though.

    • mmasse

      The only parts that I could find is the replacement kit for the DI which adds another $400 to the cost. Is there another kit available that you have a link for?

    • Not that I know of mmasse. That’s what I meant with my comment, it’s usually a kit replacement and not as “ground up” as DI can be.

  • Steve

    Hey Bryan i have a question. The bolt carrier group you have listed in the article is for full auto M-16. I know it will fit but if i wanted to put one in my AR is there anything else i would need to upgrade? Or any weird law i would be breaking. I live in Virginia beach. Thanks Man and thank you for your service.

    • Chuck

      While the M16 bolt won’t function full auto without the rest of the full auto parts and an extra hole, don’t do it. I am NOT a lawyer, but the word I’ve gotten is that the ATF gets very upset about any full auto part being on the same property as the semi-auto. You might want to look up “intent to build a machine gun” and the associated penalties.

    I am going to build an SBR. Am I going to have to pay tax on the lower and the short barrel?

  • Thomas

    It seems like you can select either the drive pin punches or the roll pin punches/roll pin holders. You don’t really need both. Is that correct?

    Also, you seem to be missing a castle nut from your parts list unless I am missing it.

    Any idea if CRC is still in business? The link to their site brings up a page where you can see pics and get an order form but there’s no address to send it to and no phone number to call…there is an email address but I didn’t hear anything back…may have been caught by the junk filter though. Anyway, the paint job looks great so I’d like to have some parts done. Also, excellent articles here…I used it to make not only a 5.56 but a 300 AAC Blackout as well…

  • Gary Brock

    Yup – You are missing a castle nut from the parts list. I got to the buttstock installation part, and, guess what? No castle nut. So… I’m ordering the part, and will start the next phase of my build when that comes in… 🙁

    • Thanks for the heads up Gary, we’ll make sure that gets added in there. Sorry you have to wait on one!

  • Lee

    The barrel you recommend has a 1:7 rifling ratio, I found an alternative barrel that has a 1:9 rifling ratio, what would be the negatives in the 1:9 as opposed to the 1:7?

  • Keith

    I just finished my first lower. After following the videos on ITS it was so easy. They did a great job thanks. I got all my parts at Machine gun tours in Denver total cost was around $400.

  • Ryan

    I am just starting to get the parts off of here for the build! I’m excited to finally get started.

    A quick question: On here it says that a 14.5″ barrel was used, if I want to use a 16″ barrel, would I need any different parts from those listed above? Thanks in advance!

  • JOE GONZALEZ

    Having only recently found your site, I have to ask are the lowers still available to purchase?

    • Unfortunately they aren’t. They were a limited run available for members although they may come up again. Although, it may be a bit hard to find a lower at the moment.

  • Ryan Edmondson

    just finished building my lower last night. Thanks for the great series. now onto an upper. thanks for all the great info guys. keep up the great work!

  • Andy Head

    Do you have a complete parts list to build the AR-15? if so would it also have prices and points of contacts to purchase the parts from Dealer/manufacturer?

  • Roger Ronas

    Question
    You mention that the permanent attachment of the compensator to the barrel must be done by gunsmith. Is that law or could a diy guy be able to do it to satisfy the law?

    Thanks
    Roger

    • It’s not the law Roger, just a recommendation so you don’t have to buy the equipment to do that yourself. If it’s something you can already do on your own, then bonus 🙂

    • Roger Ronas

      Thank you. I would then assume as it is part of the upper, I could have a friend drill and weld without an FFL as long as it’s not attached to the lower.

    @Bob Smith   – While I agree with you, for the most part, there is the whole State of the Union address where Obummer  promised to slam through his legislations, even if it means bypassing Congress.  So yes, Obama has made the threat to slam through laws without Congressional approval.  He has no regard for the American process.  It’s his way, or the highway… and that is almost a direct quote.

    @Bob Smith   if you do not believe Obama is causing money problems on purpose then you are either very stupid or are drinking to much of the cool aid. keystone pipe line and gas prices are just first to come to my mind.

  • Dick Brackett

    I just finished the assembly of a Del-Ton M4 , (AR-15) kit and was ready to zero in the sights. Imagine my surprise to learn that my “complete kit” does not include a rear sight. I was told by the nice young man at Midsouth Shooter’s Supply that no one includes the rear sight in their kits. Since I am not an insider of the kit industry, I trusted the language of the ad. Big mistake! If you are contemplating the purchase of such a “compete kit,” be aware of this. Also, if you are looking to buy a complete car, check to make sure it has all four tires and a rear windshield, if you follow the same logic. Good luck!

    Nice info! Very appreciated, I just downloaded prints from Rifleconnction.com and plan on starting my 1st lower from billet scratch!

    Hi there,

    Thanks for the great information. I see that this build is four years old and was wondering if it is still up to date or if there are parts that you would change at all. Looking at starting to buy parts and was curious. 

    Thank you!

    Do you sell the entire rifle kit as shown above minus the hydrographics?  How much?

    Any idea of a ballpark # for the cost for all parts to build a m4 rifle?  Excluding bolt ons (sites/grips…) thanks

    Look at these pliers that work like a press: https://www.youtube.com/watch?v=q11mziNfzmc
    I ordered some Kobalt that do the same thing: http://www.amazon.com/Kobalt-2-Piece-Magnum-Grip-Pliers/dp/B00A0KVY46?ie=UTF8&psc=1&redirect=true&ref_=oh_aui_detailpage_o02_s00

    Any chance of doing a similar article on building a Glock clone with an 80% lower frame?
