Details

The Coldfire 8.5-inch Pistol-Gas 1:8 .300 BLK AR-15 Freefloat M-Lok Handguard Pistol Upper Build Kit is crafted for precision and reliability. It features an 8.5-inch heavy barrel made from 4150 Chrome Moly Vanadium with a pistol gas system and a 1:8 twist rate, making it compatible with .300 Blackout ammunition. The barrel includes a 5/8x24 thread pitch for suppressor attachment or muzzle devices, and its parkerized finish ensures durability.


The upper receiver is constructed from 7075-T6 aluminum with anodized finish, incorporating M4 feed ramps for improved round feeding. Accompanied by a freefloat M-Lok handguard measuring 7 inches, this kit offers a lightweight yet robust design, providing versatility and mounting options for accessories. The kit includes a micro low-profile gas block and a GI birdcage flash hider, completing an upper assembly that meets the needs of the modern gunsmith.
