Mil-spec AR 15 rifle kits available in 5.56 NATO and .223 Remington.
AR 15 rifle kits provide a cost-effective way to build a custom AR-15. Our AR kits are packaged so you get every piece, part and pin required for your build, except for a stripped lower receiver (80% lowers are optional). Investing in an AR 15 rifle kit allows you to avoid FFL dealer mark-ups and premium prices from name brands, while getting your hands on the same, quality components in the exact configuration you want.
Our AR 15 Rifle Kits come with barreled upper assemblies. You don’t need to buy gunsmithing tools to install your barrel or handguard — we’ve already done that for you.
Completing your kit requires a completed 80% lower (available on the product page) or a stripped lower receiver purchased from an FFL. Install the included lower parts kit in your lower receiver to make your rifle kit functional.

All barreled upper receivers are ready to install out of the box. Each kit includes fixed, A2-type front sights or no sights, low-profile gas blocks, threaded muzzle devices, and Keymod, Picatinny, or M-LOK handguards.
