Lenny Magill shows off the new MCK for Glock 20 and Glock 21
Lenny Magill reviews the MCK Micro Conversion Kit for the Glock 20 (10mm) and Glock 21 (.45 ACP). The kit, formerly known as Roni, transforms large-frame Glocks into a pistol brace platform. Key features include a front-mounted spare magazine holder, an integrated charging handle, and a spring-activated locking bar for secure pistol retention. Magill also discusses personal modifications for comfort and clarifies its legal status as a pistol brace.
