.308 AR Fulton Armory Barrel


Our .308 AR match grade barrels are designed for DPMS, Remington, Bushmaster, and FA pattern rifles. These barrels feature a barrel extension and hybrid match chamber compatible with both 7.62x51 NATO and .308 Win.  Offered in a variety of contours, these barrels are manufactured from 416R Stainless Steel or Chrome Moly (Ultralight only). Chambers are finished, but barrels should be headspaced and installed by a qualified gunsmith. Gas lengths are designed to accommodate Armalite length gas tubes (.25" longer than standard AR-15 gas tubes).

Please note that although many .308 AR bolt manufacturers advertise their bolt as compatible with DPMS pattern .308 AR rifles, lug and bolt face tolerances often vary widely between different manufacturers (as opposed to the AR-15, where there is a uniform industry standard). Criterion barrels are gauged at the factory with Fulton Armory .308 AR bolts. We have also had success in demo rifle testing with bolts from DPMS and JP Enterprises. If you have any questions regarding bolt compatibility, please email us at contact@criterionbarrels.com.
