Chiappa's MFour-22 is a rimfire replica of the proven M4 Carbine rifle. Featuring a 16" barrel with an M4 profile, it is designed for use anywhere lightness, speed of action, mobility and affordable plinking are required. The inner components are made of tempered and polished steel. The upper and lower receiver are made of high-resistance polymer and may be coupled only with each other. Many of the parts are Mil-Spec, including the M4-style fixed stock, pistol grip, front sight, removable handguard, charging handle, magazine, magazine button, fixing pins, sling swivel, and ejection port. The MFour has a non-functional compensator which is not threaded and attaches to barrel with a set screw. It has a 28+1 capacity.
