After rigorous testing in both the factory and in the field, the team at Adams Arms, the manufacturer of premier piston-driven AR-15s and small frame .308’s, has selected Clenzoil Field & Range as their preferred firearm maintenance product. In addition to using Clenzoil Field & Range in the factory, Adams Arms will also be including a 0.25 oz. bottle of Clenzoil with every rifle, upper, and slide that leaves their facility.
