Don't risk your .223/5.56 barrel firing lead bullets through it with a .22 conversion kit (or suffer the last of accuracy because of the fast twist rate). This Gen 2 M4-22 upper assembly from Chiappa will pin onto virtually any standard AR-15 lower and is designed to properly handle the .22 Long Rifle cartridge. Extremely accurate, thanks to a proper 1:16" twist rate, the assembly includes a blowback design bolt and carrier. The quad rail hand guard offers lots of real estate for favorite accessories or sights.

"Hand guard needs shimming for the upper rail to match the upper receiver. upper receiver and hand guard are plastic. muzzle break was not attached. awkward balance."
