Description

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 cartridges such as the 22 Nosler and 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.

    Great barrels from a trusted company (Proof Research and Evolved Ballistics)

    Posted by Derik Sherlund on Oct 12th 2021

    I ordered two barrels, both .308, one for a customer and one for myself. Paul gave no hassle and has always been upfront regarding shortages and time-frames. The barrel shoots like a dream out of my build and everything was completed timely with no miscommunications or over-promised/under-delivered services. Evolved Ballistics and Proof Research will always be my go to for top-tier parts and service.
