Criterion Hybrid Contour Match Grade .308 AR Barrels are ideal for those seeking extreme accuracy without the added weight of a heavy barrel contour. These barrels feature a M118LR chamber, which has a longer throat that helps to improve the performance of loads utilizing heavier bullets, ultimately serving to reduce wind drift when fired at longer ranges. The configuration of these barrels is designed to accommodate either .308 Winchester or 7.62x51 ammunition, and they come complete with an installed barrel extension.

These barrels are compatible with DPMS, Remington, and Fulton pattern rifles, and they accept muzzle devices with a 5/8x24 thread. An indent is provided opposite the gas port to enable easy installation. The chambers are finished, but it is recommended that headspace be checked prior to installation.

Stainless steel variants of these barrels are available in 20 and 22 inch lengths. They are button rifled and have been hand-lapped to ensure consistent bore uniformity. The 20" Hybrid utilizes a 0.750" gas block, while the 22" Hybrid utilizes a 0.875" gas block. It is important to note that gas blocks are NOT included with these barrels.
