American Defense MFG .308 AR match grade barrels are designed for DPMS, Remington, Bushmaster, and ADM pattern rifles. These barrels feature an M4 barrel extension and M118 LR match chamber compatible with both 7.62×51 NATO and .308 Win ammunition. Offered in a mid-weight Hybrid or Heavy contour, these barrels are manufactured from 416R Stainless Steel featuring a salt bath nitride finish for corrosion resistance, reduced maintenance and enhanced accurate life. The barrel is hand lapped prior to finishing to provide the most consistent bore dimensions possible. Each of these barrels is dimpled for set screw .750 gas blocks. Chambers are finished, but barrels should be headspaced and installed by a qualified gunsmith.Av
