AR-15 Spare Parts Organization Schematic for the Obsessive Compulsive

By Bryan Black

AR-15 Spare Parts Organization

In my previous article about AR-15 Spare Parts Organization, there were a lot of comments from readers that wanted to see a detailed photo of the layout, as well as links to each specific part. It was a lot of work, but I’ve managed to put together a list of links to every spare part in the organizer and have even created interactive, clickable photos below with links and a description of each part as you hover over them.

For those of you just now seeing this for the first time, my previous article highlighted my addiction for organization, which carries over to the spare parts I take with me shooting. When I’m at a course or even shooting with friends, I like to have everything I need to keep everyone’s guns running. While I’ve never come close to needing everything in here, I follow the Boy Scout motto; “Be Prepared.”

If you’re looking for the same Made in USA plastic organizer that I used, you can get the Akro-Mils 6318 Case, available here from Amazon for around $20. The top section has 42 individual small compartments and the bottom section has another 20 compartments. The top section compartments are also secure enough to keep small parts from rolling into another compartment and get mixed around. The section dividers are adjustable as well, should you find yourself with odd shaped items.

Most of the links above are from Brownells, which has great deals on individual parts. Bravo Company USA is another one of my spots to shop for parts and is where I buy my complete MPI’d AR Bolt Assemblies from.

If you haven’t seen it yet, be sure to take a look at our DIY AR-15 Build Series for tips on parts to purchase and of course how to build your own complete AR-15 from a stripped lower receiver.
