Stainless steel gas block is built to the same dimensions as the original factory part for an easy drop-in fit on a Ruger Mini-14 or Mini Thirty. Rust resistant, natural dull silver finish blends with factory stainless steel rifles and provides a nice visual contrast on blued rifles. Easy installation with simple hand tools, using the factory gas block mounting screws. Permanently attached sling loop accepts slings up to 1" wide. Gas flow is non-adjustable. Models available to fit rifles with pre-181 serial number .562" O.D. barrels or .625" O.D. barrels.
