Ar-15/M16 Gas Piston Conversion Kit - Fail Zero Mid-Length Gas Piston Kit

Drop-in gas piston conversion kit installs in only five minutes and improves the reliability and function of your AR-15 by eliminating fouling caused by gas venting into the receiver. Rifle runs cooler, with less frequent need for cleaning and less wear on carrier and bolt - resulting in longer service life from these critical parts. The unique, kidney-shaped cross-section of the piston and piston chamber provides extra mass and surface area to evenly spread out gas pressure and reduce felt recoil, allowing you to stay on target for rapid follow-up shots. Installs in minutes on both semi- or full-auto/burst rifles with a barrel O.D. of .875" or less. No need to remove gas block/sight Mfg: Osprey Defense SPECS: Steel, black oxide finish.

Ar-15/M16 Gas Piston Conversion Kit - Gas Piston Conversion Kit, Mid-Length

Drop-in conversion kit replaces the standard direct impingement gas system with a reliable, positive cycling piston system.
