Proof Research AR-Type Carbon Fiber BarrelsWe have designed our AR barrels with the goal of improving performance and reliability in the AR platform. Our Caliber Matched Gas System (CAMGAS) results in a gas system that is tuned specifically for the cartridge and length of the barrel. The AR 15 Platform was originally designed around the 223REM and 5. 56NATO cartridges and the AR 10 was designed around the 308 Win 7. 62NATO round. With higher performance cartridge such as the 6. 5 Creedmoor,
We have designed our AR barrels with the goal of improving performance and reliability in the AR platform. Our Caliber Matched Gas System (CAMGAS) results in a gas system that is tuned specifically for the cartridge and length of the barrel. The AR-15 Platform was originally designed around the 223REM and 5.56NATO cartridges and the AR-10 was designed around the 308 Win/7.62NATO round. With higher performance cartridge such as the 6.5 Creedmoor, the bore pressure remains higher further down the barrel. By moving the port location, we ensure that the gas system pressure is the same as what the AR platforms were originally designed around. The result is a recoil impulse that is noticeably softer, less fouling in the receiver, increased reliability of extraction, and less wear and tear on brass. This helps keep you on target and shooting while taking advantage of the latest high performance cartridges.
* Barrels are guaranteed for headspacing to the specifications of the JP Enterprise Enhanced Bolt.
* It is recommended to double check and ensure proper headspace before firing your rifle.
* We recommend the use of full mass components throughout (full mass bolt, buffer, and springs).
* All barrels with Intermediate, Rifle +1, Rifle +2, and Rifle +3 gas systems include the proper gas tube.
* Our AR-10 barrels use a deep feed system that makes the feed ramps compatible with the feed ramps in the lower receivers of both DPMS and Armalite style rifles.
* 6 ARC Disclaimer - It is our recommendation to refrain from shooting bullets that weigh less than 100 grains.
