ADM Lightweight Contour AR-15 Barrel
Criterion-manufactured ADM barrels are offered in a 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. Each barrel is salt bath nitrided for enhanced durability and corrosion resistance. A dimple is machined opposite of the gas port to allow for easy installation of set screw gas blocks.
Chambers are finished, but barrels should be headspaced and installed by a qualified gunsmith.
