Proof Research PR15 14.5″ .223 Wylde Mid Length 1/7 Twist AR 15 Barrel

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.

• Extreme Pressure Resistance An optimum combination of high tensile strength along with requisite toughness to withstand extreme chamber pressures encountered during firing
• Long-Lasting Excellent erosion wear characteristics and corrosion resistance
