Davidson Defense Blackhill 20-inch Rifle-Gas 1:8 6.5 Creedmoor AR-10 M-Lok Rifle Complete Upper Build

Blackhill 20-inch Rifle-Gas 1:8 6.5 Creedmoor AR-10 Complete Upper Build

This Davidson Defense Blackhill upper delivers precision rifle performance in 6.5 Creedmoor with a 20-inch heavy profile barrel and rifle-length gas system. The complete upper includes everything needed for assembly except the lower receiver: upper receiver, bolt carrier group, charging handle, and all gas system components. The free-float handguard eliminates contact with the barrel, supporting consistent accuracy across extended shooting sessions.

Key Features

• 20-inch heavy profile barrel with 1:8 twist rate, optimized for 6.5 Creedmoor precision loads
• Rifle-length gas system with low-profile gas block for reliable cycling
• Free-float M-LOK handguard eliminates barrel contact for improved accuracy
• Recoil Technologies nitride bolt carrier group compatible with .308 Winchester, 6.5 Creedmoor, and .243 Winchester
• .308 Standoff muzzle brake with 5/8x24 thread pitch
• LR-308 billet upper receiver with DPMS low profile pattern and Type III hardcoat anodize

Perfect For

• Long-range precision shooters building a 6.5 Creedmoor AR-10 platform
• Hunters seeking accurate mid-range to extended distance capability
• Builders selecting a complete upper assembly for LR-308 lower receivers
• Shooters valuing barrel consistency and gas system reliability

Precision-Focused Design

The 1:8 twist rate stabilizes heavier 6.5 Creedmoor projectiles, making this configuration suitable for precision applications where velocity and accuracy matter. The heavy barrel profile resists heat buildup during extended shooting, maintaining point-of-impact consistency. Rifle-length gas systems provide softer recoil impulse and longer dwell time compared to carbine-length alternatives, supporting reliable function across a wider range of ammunition specifications.

Free-Float Accuracy Foundation

The 19-inch free-float M-LOK handguard isolates the barrel from external contact, eliminating variables that degrade accuracy. M-LOK attachment points distribute weight and accessories evenly along the handguard without stressing the barrel or upper receiver. This design approach supports repeatable accuracy whether shooting from bench rest, bipod, or tactical positions.

LR-308 Platform Compatibility

This upper receiver follows DPMS low profile pattern specifications, compatible with most LR-308 lower receivers. The Recoil Technologies bolt carrier group works across .308 Winchester, 6.5 Creedmoor, and .243 Winchester chamberings, providing flexibility if you decide to build additional uppers later. Verify lower receiver pattern before assembly to ensure proper fit.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Bolt carrier group and charging handle are included. Lower receiver not included.
