This complete upper includes an 8.5 inch 300 BLK barrel, 7 inch M-Lok freefloat handguard, complete bolt carrier group, and charging handle. The upper receiver is forged 7075-T6 aluminum with anodized finish. The barrel is 4150 Chrome Moly Vanadium with parkerized finish, 1 in 8 twist rate, and 5/8x24 threads. The bolt carrier group is 9310 alloy steel with nitride finish.
This upper includes all components needed for immediate installation on a compatible AR-15 lower receiver. The bolt carrier group and charging handle are included, eliminating the need for additional upper components.
The 8.5 inch heavy HBAR profile barrel provides increased rigidity and heat dissipation. The parkerized finish offers corrosion resistance and surface hardness. The pistol gas system is matched to the barrel length for reliable cycling with both supersonic and subsonic ammunition.
The 7 inch handguard features M-Lok attachment slots for modular accessory placement. The freefloat design isolates the barrel from handguard contact. The 6061-T6 aluminum construction maintains a lightweight profile while providing structural integrity.
The 9310 alloy steel bolt carrier group features a nitride finish for enhanced corrosion resistance and reduced friction. The BCG is paired with a Mil-Spec M4 charging handle for complete upper functionality.
Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws.
