CAA Set to Release the Gen 3 MCK Pistol Conversion Kit for Glock Models

The ability to add a stabilizing stock to a pistol adds a whole other level of control. However, the ability to completely convert your pistol is a game-changer. The CAA Gen 3 Micro Conversion Kit (MCK) is about to change the way you shoot your Glock. This not only changes range day but home defense as well.

The CAA Gen 3 MCK for Glock

Following on the heels of its previous Micro Conversion Kits for other pistols, CAA addresses user concerns with the Gen 3. Well, concerns might not be accurate, they were more “wish list” items, but they changed the MCK for the better.

The most significant change is the ability to place your pistol into the chassis with your own RMR optic installed. As a result, users can stick with the optic platform they are accustomed to, without the need to re-zero. However, if you do not have an optic installed, the Gen 3 provides 2 removable Picatinny rails for the addition of an optic of your choice.

Perhaps one of the more practical additions is the “Car Wash System” to keep your pistol slide clean. Previous versions of the conversion kit required regular cleaning due to fouling of the slide from carbon buildup. However, the new internal system features a brush/bristle system that removes the carbon buildup, keeping the slide clean as it cycles. In addition, the system does not damage the slide’s finish.

An available rear Glock backplate adaptor allows for the addition of an external charging handle. As a result, users will no longer need to rely on the slide serrations. For true ambidextrous functionality, you can place the handle on either the right or left side.

Likewise, the folding stock can be folded to either the right- or left side of the pistol. Correspondingly, the pistol can still fire, even with the stock still folded. Additionally, the stock can be raised for use with rail-mounted optics or lowered for use with pistol-mounted RMR.

The Gen 3 is compatible with the Glock 17/19/19x/20/21/22/23/25/31/32/45. However, it is not compatible with Gen 1 or 2 Glock models due to the lack of forward Glock universal accessory rail.


The CAA Gen 3 MCK for Glock will be available soon, with an MSRP of $349.00 – $539.00, depending on options. For more info, please visit
