CAA USA MCK 3.0 Micro Conversion Kit - Glock 17 / 19 / 19x / 22 / 45

The CAA MCK Gen 3 Micro Conversion Kit redefines pistol transformation by turning compatible Glock platforms into a stabilized, optics-ready carbine-style system. Engineered for maximum adaptability, the Gen 3 introduces a redesigned charging system, expanded optic compatibility, and enhanced ergonomics—giving shooters a faster, more versatile shooting experience across multiple calibers and Glock generations.

With a redesigned ambidextrous stabilizer, improved cleaning system, and upgraded mounting architecture, this platform delivers faster target acquisition, improved control, and streamlined maintenance.
