This complete upper includes a 10.5 inch 6.5 Grendel barrel, 10 inch M-Lok freefloat handguard, complete 6.5 Grendel Type II bolt carrier group with QPQ nitride finish, and charging handle. The upper receiver is forged 7075-T6 aluminum with anodized finish. The barrel is Bear Creek 4150 CrMoV steel with phosphate finish, 1 in 8 twist rate, and 5/8x24 threads. The handguard is aircraft grade aluminum.
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 10.5 inch HBAR profile barrel is chambered in 6.5 Grendel with a 1 in 8 twist rate for projectile stabilization. The phosphate finish offers corrosion resistance and surface hardness. The pistol gas system is matched to the barrel length for reliable cycling. The barrel features 5/8x24 threads with an included GI birdcage flash hider.
The 10 inch handguard features M-Lok attachment slots for modular accessory placement. The freefloat design isolates the barrel from handguard contact. The aircraft grade aluminum construction maintains a lightweight profile while providing structural integrity.
The complete bolt carrier group is specifically configured for 6.5 Grendel Type II chamberings. The QPQ nitride finish provides enhanced corrosion resistance and reduced friction. The BCG is paired with a Mil-Spec charging handle for complete upper functionality.
Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws.
