Product description
The CAA MCK Gen 2 conversion kit for the Glock 20 and 21 is sized for Glock's large frame, the one behind the 10mm Glock 20 and the .45 ACP Glock 21. Each MCK version matches a specific pistol, and this one is built around that bigger frame. It takes your pistol as it is, with no disassembly.
Fit comes down to the rail. CAA lists the Glock 20, 21 and 21 SF models that have the Universal Glock Rail. Models with a Picatinny rail are not compatible. Look at your frame before you order, because that one detail decides whether this kit works for you.
The build pairs an aluminum barrel shroud with a polymer body. Sights or optics mount on the top Picatinny rail, while side rails carry extras such as thumb rests. You work the slide from the chassis with the built-in charging handle. The slide release stays exposed, a front holder keeps a spare magazine close, and CAA describes the handling as ambidextrous.
You can pick OD Green, Tungsten Grey, Black or FDE Tan. The MCK is made in the USA. CAA's 1-year warranty kicks in when you register the kit with CAA no later than 30 days after purchase. You can buy it without an FFL. State and local laws on these kits vary, so look yours up first.
