Details

The Davidson Defense Apiar .300 BLK AR-15 Pistol is a compact and robust firearm featuring an 8.5-inch heavy barrel with a 1:9 twist rate, optimized for .300 Blackout ammunition. The pistol-length gas system ensures reliable operation, while the barrel, constructed from 4150 Chrome Moly Vanadium and finished with a parkerized coat, provides durability. The upper receiver is made from 7075-T6 aluminum and features M4 feed ramps for consistent feeding.


This build includes a freefloat 7-inch M-Lok handguard, allowing for flexible mounting options without compromising the barrel's accuracy. The assembly utilizes a complete AR-15 Bolt Carrier Group made of 9310 alloy steel, nitrided for longevity. Equipped with an SB Tactical SBA3 adjustable pistol stabilizing brace and supported by a mil-spec heavy-duty six-position buffer tube, this kit combines stability and practicality, perfect for gunsmiths who value freedom and performance in .300 BLK configurations.
