The CMMG® MK4 / AR-15 .22 LR 10-Round Magazine is a conversion magazine compatible with .22LR conversion kits and CMMG MK4/Mil-Spec AR-15 lower receivers. The steel wire spring and hi-vis polymer follower deliver smooth, jam-free operation, while the removable floor plate allows for quick maintenance and cleaning when required.
