Perfect For

• Hunters pursuing medium to large game at extended ranges
• Precision rifle builders seeking a compact, accurate platform
• Shooters wanting 6.5 Grendel performance in a standard AR-15 lower receiver
• Those prioritizing accuracy and barrel quality over maximum capacity

Precision Platform for Extended Range

The 1:8 twist rate stabilizes heavier 6.5 Grendel ammunition, making this upper ideal for shooters pushing beyond 300 yards. The freefloat barrel design isolates the barrel from handguard contact, reducing vibration and improving shot consistency. Parkerized barrel finish provides durable corrosion resistance for field use.

Compact Carbine Configuration

At 16 inches, this barrel length balances velocity and handling. The carbine-length gas system pairs with the micro low-profile gas block to manage recoil efficiently without excessive noise. The Guntec micro compensator helps redirect muzzle rise while staying compact for close quarters or vehicle-mounted setups.

M-Lok Modular Ecosystem

The 15-inch M-Lok handguard supports tactical accessories without rail bloat. The partial top Picatinny section accommodates standard optic mounts, while M-Lok slots along the sides and bottom accept vertical grips, light mounts, and sling attachments. This modular approach keeps the rifle lightweight and customizable.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. BCG and charging handle are included with this complete upper. Lower receiver not included.
