Brownells Brownells Brownells 75th Anniversary - A Shooting Heritage

Single spiral of spring steel loops around the bolt three times and leaves no path for gas leakage. Replaces conventional three-piece "piston ring"-style sets that can accidentally line up, causing a major leak from the gas expansion chamber in the carrier.
