This super-compact AR 15 Pistol Kit is the perfect way to build a heavy-duty, close-quarters shooters with one box of parts. The included 4150V heavy barrel affords laser accuracy with a versatile 1:7 twist rate. A lightweight 7” M-lok handguard keeps things maneuverable and offsets the weight of that bomb-proof barrel.

In your hand, you’ll find a quality polished, enhanced trigger seated in a mil-spec lower parts kit. Out back, a convenient 5-position buffer tube accommodates a high-speed SBA Pistol Brace for better shot placement and recoil control. Finish the kit off by picking a mil-spec forged or billet 80% lower, and you’ll have everything you need to complete your build right away.
