American Defense MFG AR15 Barrels have the following features:
4150 CMV (chrome moly vanadium) steel, 1⁄8 twist, .223 Wylde chambered, Nitride Finish. The ADM barrel provides the durability of the best material in the family of “Ordinance Grade Steels”, coupled with a 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. The Wylde chamber ensures the barrel is able to shoot to its accurate potential while safely and optimally handling .223 Remington, and 5.56mm Nato ammunition. Barrels are offered in lightweight type contour which promotes ease of handling, as well as typically providing sub MOA accuracy with match grade ammunition and an experienced shooter from a bench rest.
