Details

The Coldfire 8.5-inch .300 BLK AR-15 Full Build Kit is engineered for gunsmiths seeking a compact and reliable pistol system. Featuring an 8.5-inch heavy barrel crafted from 4150 Chrome Moly Vanadium with a Parkerized finish and a 1:8 twist rate, this kit ensures precision performance. The pistol gas system uses a micro low-profile gas block and is fitted with a 5/8x24 TPI GI Birdcage flash hider for effective muzzle control.


The upper receiver, constructed from anodized 7075 T6 aluminum, incorporates M4 feed ramps for reliable ammunition feeding. A 7-inch freefloat M-Lok handguard provides ample mounting options while maintaining minimal weight. The included Gauntlet Arms Brace, made of high-strength black polymer, offers stabilization for the shooter. The kit also includes a mil-spec charging handle and a complete bolt carrier group made from 9310 alloy steel with a nitride finish for durability.
