Converts Your AR To A Smooth, Clean, Reliable Piston-Operated Tactical Carbine
Drop-in ready upper receiver assembly is the fast, easy way to convert your AR to a gas piston operated tactical carbine with a low-profile accessory rail system. The MK116 uses a "long stroke" piston to reduce felt recoil and provide smooth, consistent cycling for more comfortable shooting, and faster return-to-target for follow-up shots. Improves reliability, too, by keeping carbon fouling out of the receiver.. The quad rail system clamps the barrel securely to the receiver to produce an ultra-rigid, yet compact platform that keeps the piston system properly aligned. Provides over 40" of accessory mounting space, including 16" of uninterrupted top rail that extends forward of the gas block. The bottom rail and each side rail has a receptacle at the rear for push-button, single-point sling attachment. Comes with plenty of Tangodown SCAR rail covers to cover unused portions of the rail. The cold hammer forged, chrome-lined 16.1" barrel is chambered for 5.56mm NATO ammo, with M4-type feed ramp cuts in the barrel extension to aid in reliable chambering. A PWS FSC556 flash suppressor/compensator minimizes muzzle flash and counteracts muzzle rise, further aiding in fast follow-up shots.
