The popular MCK or Micro Conversion Kit series from CAA, allowing one to have a stable shooting platform, will soon be released as third generation model. What’s even better is that CAA has taken into consideration the optics ready slides of pistols for the MCK Gen 3, in this case Glock pistols, and they can be readily dropped into the kit and readily be used to aim with optic, such as the RMR quickly.

What’s more? The CAA USA GEN 3 Charging Handle, which is sold separately, allows owners to use any aftermarket slides, sights or optics inside the MCK. While made for a wide variety of Glock pistols, it is not compatible with Gen 1 and Gen 2 models.

But if you want to mount optics on the MCK Gen 3 itself, all you need to is install the removable Picatinny rails and mount the optics on them. As for handling, the folding stock can be folded left or right. You can also attach a larger suppressor, such as a 1.57” one on the pistol.

With its pre-order promo, they are throwing in Free Thumb Rests, Backup Sights & MCK Tin Mancave sign. Options are for the Gen 3 stabilzer or Gen NFA Stock. As for color options, then better brace yourself, they offer a long list of color options ranging from the usual colors of black, OD, FDE, to white, orange, blue, red, pink, and even Ghost camo.

We wonder if Glock pistols made by VFC and Tokyo Marui can readily fit in the MCK Gen 3 and we assume they do as they have been designed to the exact dimensions as the real world ones. We believe the GHK version can readily fit too.

Could the MCK Conversion Kit Get Any Better? Meet the MCK GEN3

Based on the wildly popular MCK GEN 1 and 2 Conversion Kits, the MCK GEN3 is the ultimate combination of engineering innovation AND customer feedback.

Pompano Beach, Fla. (March 2022) – CAA USA, designers, and developers of the world-famous MCK/Micro Conversion Kit, is pleased to inform its loyal and new customers that the latest generation of the MCK, incorporating all the latest technologies and wish-list features, is now available in the new MCK GEN3.

Dynamic new features on the MCK GEN3 include:

• MCK “Car Wash System”
• Ability to use MCK with Micro Red Dot slide-mounted optic installed on a pistol
• Ability to aim and shoot with the RMR while attached to slide inside the MCK
• Stabilizer height adjustability
• Ambidextrous folding stock right AND left
• New charging handle system
• New easily removable front adaptor
• Removeable rear and front top Picatinny rails
• Able to use a larger 1.57” suppressor on the pistol

LTC. (Ret.) Mikey Hartman, CEO of CAA USA, explained the thought process behind the new MCK GEN3 Conversion Kit. “Each new generation MCK we make we try to incorporate intelligent suggestions that we get from our loyal customers and fans: the MCK GEN3 was no different. The fact that not only can you now insert your handgun with a red dot slide mounted optic, but you can also aim with it via the MCK, there will be no need to disassemble your optic as you had to do in previous generations. The internal cleaning mechanism along with the dual folding Stabilizer/Stock make the Gen 3 the best conversion kit we ever have made.”

One of the top items on the MCK wish list was a way to keep the red dot optic integrated on the pistol while incorporating it into the conversion kit. The MCK GEN3 chassis not only allows a seamless and perfect fit of the optic-mounted pistol, but the user will not have to zero the optic when using it with the conversion kit. Simply insert, lock, and the user is ready, pistol-mounted optic and all.

Another common concern was the fouling of the slide during operation and the need to remove the pistol for cleaning more often than desired. CAA’s engineers and designers have come up with a brilliant solution, the CAA “Car Wash System.” Similar to drive-through car washes, the built-in pistol cleaning system uses a brush/bristle system to clean the front of the slide during cycling, removing carbon build-up, without damaging the slide’s finish.

Speaking of cleaning, the new front adaptor now shields the internal parts of the MCK from any carbon build-up. Plus, the adaptor is easily removed for cleaning.

While the stabilizer/stock on the MCK Conversion Kits is unique and the best in the nation, CAA’s left-hand customers weren’t being serviced. Now, the stabilizer/stock on the MCK GEN3 is ambidextrous, folding either right or left, and can be fired while folded for immediate response to a threat. The MCK GEN3 stabilizer/stock not only folds left or right but also adjusts in height. Two height options are available: one (lower position) option for using when shooting with an RMR/slide-mounted optic, and two (upper position) when employing any type of red dot/optic on the top of the Picatinny rail.

Additional new features found only on the MCK GEN3 include a new charging handle system that uses a backplate adaptor, thus negating the reliance on the slide serrations to cycle the handgun; removable rear and front top Picatinny rails that allow the user to better customize their MCK GEN3 chassis; and an improved spare magazine holder that operates with a magazine catch and magazine release button.

“The MCK GEN 1 and 2 took America by storm,” Hartman continued. “We will continue to bring new models to the market every two months while continuing to maintain the title of the most popular handgun Conversion Kit in the world!”
