Float the forearm. Medium speed reloads or Federal Blue box ammo. Tighten forearm screw till it shoots 3/4", start a bit more than hand tight and work up. These are unreal rifles and parts are available to rebuild them. There is an update on the gas piston. Pull it apart and clean it. Mine has at least a thousand rounds thru it, altho a 308. Like shooting a varmint rifle recoil wise and damn near as accurate. The forearm screw is the key to my rifle.
