Proof Research has designed these barrels with the goal of improving performance and reliability in the AR platform. The Proof Research 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.
CARBON FIBER-WRAPPED PERFECTION
The patented manufacturing process begins with full-profile, match-grade 416R stainless steel barrel blanks that are made by Proof Research's firearms division. These blanks are then turned down to a significantly reduced profile greatly reducing weight. This reduced contour barrel is then filament-wrapped with high-strength, aerospace-grade carbon fibers impregnated with a high-thermal conductivity matrix resin developed by our aerospace materials division.
The .223 Wylde is a proprietary rifle cartridge chamber with the external dimensions and lead angle as found in the military 5.56×45mm NATO cartridge and the 0.224 inch freebore diameter as found in the civilian SAAMI .223 Remington cartridge. Rifles with a .223 Wylde chamber will typically accept both .223 Remington and 5.56×45mm NATO ammunition. Note that while the .223 Remington and 5.56×45mm NATO chambers have slightly different dimension, the cartridges themselves are identical in dimension. The chamber dimension differences are often confused with the cartridge dimensions and so it is often erroneously thought that the cartridges have different dimensions. The cartridges are loaded to different pressure levels (with the 5.56 being greater), however. (The NATO dimensions offset the higher pressure with a longer throat - often confusing some to think the cartridge itself is longer). This chamber allows the use of both pressure levels safely while also increasing accuracy potential across the range of potential pressures.
The .223 Wylde hybrid chamber was designed by Bill Wylde to exploit the accuracy advantages of the .223 Remington chambering without pressure problems or compromising the functional reliability of semi-auto weapons like the AR-15 family when using 5.56×45mm NATO military ammunition. Coincidentally, it shoots the relatively long and heavy 80-grain bullets commonly used in the Sport Rifle Competition very well and is one of the preferred chambers for that use.
