Upper Receiver Precision Rifle Kit 6.5 Cm 22 Barrel

The Knights Armament 6.5 Creedmoor Upper Receiver Precision Rifle Kit is a drop-in upper assembly built for SR-25 platform owners who demand long-range performance and precision accuracy. This upper receiver kit delivers the ballistic advantages of 6.5mm Creedmoor—superior ballistic coefficient, enhanced muzzle velocity, and milder recoil—making it a natural upgrade for hunters, match shooters, and tactical competitors looking to extend their effective range without fighting excessive muzzle rise.

The heart of this kit is a 22-inch dimpled precision barrel with a 1:8 right-hand twist, struck to balance velocity, ammunition versatility, and practical maneuverability. The 18-inch URX6 handguard is long enough to mount night vision devices, targeting systems, and rangefinders without getting in your way, while the fluted profile keeps heat signature low and maintains a rigid platform for accurate follow-up shots. Up front, the 7.62 QDC open brake hammers recoil reduction hard and serves as a direct mounting interface for Knights Armament 7.62 QDC suppressors if you're ready to go silent.

Weighing 6.9 pounds and stretching 33 inches (upper receiver only), this assembly is sized for mid-range shooters and hunters who value consistent barrel time and minimal blast signature. It's a ready-to-drop kit for existing SR-25 pattern lowers—verify your platform before ordering, as this will not work with DPMS pattern receivers.

Frequently Asked Questions

Will this upper receiver fit my lower receiver?

This is an SR-25 pattern upper receiver. It will drop onto SR-25 pattern lowers but will not work with DPMS pattern receivers. Confirm your lower's pattern before purchasing.

Can I attach a suppressor to this upper?

Yes. The 7.62 QDC open brake is threaded to accept Knights Armament 7.62 QDC quick-detach suppressors, giving you the option to run suppressed for hearing protection or sound reduction in the field.

Is the handguard long enough for my night vision and rangefinder?

The 18-inch URX6 handguard provides substantial Picatinny rail space for inline mounted night vision, targeting devices, and rangefinders without adding unwieldy length to the overall package.

What ammunition does this barrel shoot best?

The 1:8 twist rate is optimized for 6.5mm Creedmoor across a wide range of bullet weights, giving you flexibility in ammunition selection for hunting, competition, or general range use.
