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.

NOTE FROM WADE
We have many test rifles built around the proof research barrels. They perform very well as well as some of the best machine work ive seen borescoping many barrels. We belive in this product, which is why we wanted to offer it to you guys. Be sure and check out the vlog for more information on 6mm ARC and more! Keep in mind, proof provides gas tube for the 18" and 20" but not the 16". We have the superlative gas blocks and will have gas tubes soon.
