M4-22 Gen II Pro Features

Just like the MFour-22 rifle, the Chiappa M4-22 Upper Receiver Kit takes advantage of AR platform dimensions and geometry. These upper receivers will fit on any MIL-SPEC lower receiver to create a .22LR rifle perfect for plinking or training. Includes 2-28 Round Magazines.
