Today in part two of our DIY AR-15 Build you’ll learn how to install the Magazine Catch on your Lower Receiver.
While fairly simple in terms of installation steps in assembling your AR-15, it’s still important to treat this step with the same attention to detail as all the other steps we’ll be walking you through.
The function of the Magazine Catch is to properly lock in the magazine when inserted into the magazine well of the Lower Receiver and drop it free and clear when the Magazine Release Button is depressed.
If you’re a lefty or typically practice transitioning ambidextrously, you also may want to check into an Ambi Mag Release. We won’t be installing one here, but we wanted to mention that they are out there and available.
Something we’d like to add into this first assembly article are a couple of books that may help you throughout your journey in assembling an AR-15. Black Rifle and Black Rifle II are both excellent books that will supplement this series very well and go into everything from the history of the platform to the how and why.
Another book we all love around here is Green Eyes and Black Rifles by Kyle Lamb. It’s a great resource that goes into everything from history, maintenance and tactical applications.
These books are all phenomenal resources and will answer many of the questions that will no doubt come up during your assembly, plus they’re all are great reference materials to have in your library.
Lower Parts Kit
During the build of the Lower Receiver we’ll be using the Stag Arms Lower Parts Kit. As many of you may have experienced, we’ve had problems with some of the “less expensive” LPKs and have chosen the Stag Arms LPK because of the reputation we know it to have.
There have never been any issues with the trigger group in our usage and we really like the fact that it comes with an extra Pivot Pin Detent. You’ll soon find out why that’s important when we get into the (often aggravating) installation of the Pivot Pin.
Vise Bench Block
As we mentioned in the last article, the tools that we’re going to suggest in these following articles aren’t necessarily mandadory, but if you’re going to take your AR-15 build seriously we’d highly recommend them.
At the very least invest in a good Lower Receiver Vise Bench Block. The one linked here is nice due to it’s dual usage for your lower and upper by simply flipping it over.
Other than your Lower Receiver you’ll need the following parts from the Stag Arms Lower Parts Kit:
- Magazine Catch
- Magazine Catch Spring
- Magazine Release Button
- Vise (not mandatory)
- Lower Receiver Vise Block (not mandatory)
- Takedown Tool
- Place the Lower Receiver onto the vise block that’s been secured to your vise.
- Insert the Magazine Catch into the lower receiver from the port side (left) of the rifle.
- Insert the Magazine Catch Spring (no difference for orientation) and the Magazine Release Button into the starboard side (right) of the lower.
- Hold pressure against the Magazine Release Button while turning the Magazine Catch clockwise.
- Once you feel the catch grab the threads of the button you can release the button. Now take your takedown tool and depress the button further into the lower. This will allow you to turn the Magazine Catch into the proper position.
- The proper place to stop turning is when the shaft of the catch is flush with the face of the button. If it’s hanging up at all when you test press the button, you may need to turn the catch further clockwise.
- Test the catch by inserting an empty magazine into the magazine well and ensuring the catch locks into the magazine and allows it to drop free when the Magazine Release Button is depressed.

I am interested in building my first AR. I have reviewed all of the DIY videos for the build. Fantastic job. Very thorough. Do you have any new recommendations since the videos were shot? I am thinking of a slightly longer barrel length, say 20". Do you have any recommendations for the upper? I am also thinking of a solid stock. Any recommendations there would be appreciated as well.

Thanks guys! I've been interested in this for a while but haven't had the time to search out the information online. I'm really looking forward to the entire series. At some point during the build, could you maybe list the different components purchased and prices for each?
