Tippmann Arms M4-22 Conversion Kit Features The Tippmann Arms M4-22 Conversion Kit bolts onto a mil-spec AR lower turning it into a dedicated .22 LR platform without permanent modification to the host rifle. The kit s 16 inch steel barrel carries a 1:16 inch twist rate suited to rimfire ammunition and is threaded 1/2x28 to accept standard muzzle devices finished off with an A2 bird cage. A 12 inch free float M-LOK handguard gives shooters room to mount lights lasers or other accessories while keeping the barrel free of contact pressure. An aluminum charging handle rounds out the upper assembly for smooth reliable cycling. Because the conversion uses the shooter s existing AR lower it offers a low-cost way to add a .22 LR training option to a rifle already configured the way the shooter likes it. The included 25 round magazine gives extended range time between reloads useful for training drills or casual plinking sessions. Swapping between the centerfire upper and the M4-22 kit takes only the time needed to separate and reattach the upper and lower receivers. The Tippmann Arms M4-22 Conversion Kit is available for sale at GrabAGun for AR owners looking for an economical low-recoil training solution.
