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. Updates the AR to the type of operating system used on advanced weapons like the FN SCAR, Heckler & Koch G36, and HK416, as well as the highly reliable, classic FAL and AK-series rifles. Makes weapon run cooler, smoother, and more reliably, with less wear and easier maintenance. Because the gas no longer vents inside the receiver, fouling and carbon buildup are greatly reduced, requiring less frequent disassembly for cleaning. Less fouling and lower operating temperatures mean reduced wear on bolt, carrier, and receiver interior for fewer malfunctions caused by worn Mfg: Cmmg SPECS: Piston Tube, Bolt Carrier, Handguard Retainer Cap Steel, black oxide finish.
