CMMG Gen 2 Mk4 22LR 10rd Black - AR-15 Magazine

Keep your .22 LR AR-15 training sessions compliant without sacrificing the CMMG quality you already trust. The CMMG Gen 2 Mk4 22LR 10-round magazine delivers the same proven 22ARC feeding geometry and updated Gen 2 exterior styling as the 25-round variant, in a 10-round configuration suited for restricted-capacity jurisdictions or controlled-round-count training drills.

The CMMG Gen 2 Mk4 22LR 10-round magazine is a polymer magazine designed for use with .22 LR conversion kits and CMMG Mk4/mil-spec AR-15 lower receivers, featuring updated Gen 2 exterior styling in black with a 10-round capacity.

Three qualities make this the right 10-round choice for .22 LR AR-15 platforms. Proven 22ARC internal geometry from CMMG's original conversion magazine carries forward into the Gen 2 body, maintaining the reliable feeding and ejection performance that has made CMMG's .22 LR conversion system a trusted training tool. Gen 2 exterior styling aligns with CMMG's current firearm and magazine lineup, providing a purpose-built appearance that matches the aesthetic of CMMG rifles rather than looking like an afterthought. The 10-round capacity meets the requirements of restrictive-capacity jurisdictions while still allowing meaningful strings of fire for training, competition, and small-game applications.

Compatible with CMMG .22 LR conversion kits and CMMG Mk4/mil-spec AR-15 lower receivers. Not compatible with standard 5.56 upper assemblies without a .22 LR conversion kit.

Polymer construction. 10-round capacity. Black finish.

Suited for restricted-capacity jurisdictions, controlled-round-count training, new shooter instruction, and small-game hunting applications requiring a compact .22 LR magazine.
