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

Davidson Defense 6.5 Creedmoor AR-10 Complete Upper Build

This is a precision rifle-gas upper built for long-range shooting. The 20-inch heavy fluted barrel in 6.5 Creedmoor pairs with a 1:8 twist rate to stabilize heavier projectiles, while the rifle-length gas system provides reliable cycling without excessive bolt carrier speed. The LR-308 billet upper receiver follows DPMS low profile specifications, and the 19-inch free-float M-LOK handguard keeps your shooting platform stable. Everything you need is included except the bolt carrier group and charging handle.

Perfect For

• Shooters upgrading from standard AR-15 to .308 class rifles
• Builders seeking a complete upper assembly without lower receiver commitment

Long-Range Precision Ready

This upper is engineered for distance. The 1:8 twist rate stabilizes 120 to 140-grain projectiles, which is the sweet spot for 6.5 Creedmoor ballistics. The heavy fluted barrel reduces weight while maintaining rigidity, and the free-float handguard eliminates contact between barrel and furniture that would throw off shot placement. The rifle-length gas system keeps bolt carrier movement predictable, which matters when you're dialing in precision loads.

LR-308 Platform Compatibility

This upper sits on DPMS low profile receivers, which is the standard for modern AR-10 builds. The bolt carrier group works across .308 Winchester, 6.5 Creedmoor, and .243 Winchester, so if you decide to swap barrels later, your carrier cycles all three. The low profile gas block and receiver pattern ensure reliable feeding and extraction without modification.

Free-Float Handguard and Accessory Mounting

The 19-inch Crest Series handguard uses M-LOK slots along its length, giving you multiple positions for bipods, lights, or other rail systems. The free-float design means the barrel never touches the handguard, which is critical for maintaining accuracy shot to shot.

What You Need to Know

BCG and charging handle are not included. Wait, that's not right for this product. The charging handle is included. You will need a compatible LR-308 lower receiver to complete the rifle. The upper alone does not cycle or function as a complete firearm.
