Proof Research has designed their AR barrels with the goal of improving performance and reliability in the AR platform. Their 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.

Description

Hornady’s 6mm Advanced Rifle Cartridge (ARC) is the first time in history that the commercial announcement of a cartridge was preceded by adoption within the military. While Hornady has been extremely secretive about who adopted the cartridge, they can say that it is a “notable Department of Defense (DOD) entity”.

The reasons a military unit would be interested in the 6mm ARC are for its utility and mild manners that ensure long firearm life. Threats have learned to stay 500 to 600 meters away from our troops on the battlefield to be safe from the effectiveness of our 5.56mm rifles, carbines and machine guns. The U.S. military has been looking for a solution.

The 6mm ARC is unique among rifle cartridges in that it fits in an AR-15-pattern action, functions reliably out of standard-capacity 24- or 17-round magazines, and remains supersonic beyond 1,000 yards in a standard atmosphere. This allows a rifle chambered in this cartridge to be used for everything from close quarters battle (CQB) to sniper missions while simplifying logistics for the units that carry it.
