    Criterion .308 AR match grade barrels are designed for DPMS, Remington, Bushmaster, and FA pattern rifles. These barrels feature an M4 barrel extension and M118 LR match chamber compatible with both 7.62x51 NATO and .308 Win ammunition.  Offered in a mid-weight Hybrid contour, these barrels are manufactured from 416R Stainless Steel or 4140/4150 Chrome Moly Steel (for chrome lined models only). Chambers are finished, but barrels should be headspaced and installed by a qualified gunsmith. 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. Optional factory headspaced bolt/barrel combinations are available. If you have any questions regarding bolt compatibility, you may email Criterion at contact@criterionbarrels.com.
