Bolt Gas Ring McFarland 1-Piece AR-15

Mfr: FULTON ARMORY

Stops Gas Leaks & Eliminates Sluggish Bolt Performance.

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.

SPECS: Polished spring steel.
