Criterion Barrels has been, and remains, an absolute essential name in the barrel business. With over 30 years of experience, Criterion brings the expertise needed to produce top tier barrels. Their match grade product quality comes from their precision in bore and groove dimensions, and their uniformity of twist. Criterion makes some of the most affordable AR barrels without sacrificing quality or precision. Criterion Barrels are great for those looking for refined accuracy without the added weight of a barrel contour. They have also expanded their repertoire to include a variety of models, now making barrels for AR-10, AR-15, M1 Garand, M1 Carbine, M1 A, 1917, 1903, P-14 Enfield, and Savage and Remington pre-fits.

Best SellerCriterion .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.

Eight flutes are machined around the circumference of the barrel to the front and rear of the gas port. Each flute is polished to smooth jagged edges while retaining a sharp appearance. Each 416R stainless steel barrel comes complete with an M4 barrel extension and a .223 Wylde chamber designed to accept both .223 Remington and 5.56 NATO cartridges.
