MCK Gen2

SKU: 20037
$265.00 to $365.00
The updated Micro Conversion Kit Gen2 for most Gen3, 4, or 5 Glocks* is here, and it's even more awesome than the last!

Originally designed to improve one-handed shooting, the new MCK features a redesigned brace. This brace not only provides the same stability and security as the last model, it also allows the user to fire the MCK Gen2 while folded and locked!

No disassembly for the kit or your gun is required for installation! The Charging Handle is captured in the MCK for simplicity, and the external Slide Stop Lever buttons have been replaced with a cutout, so you can easily access your Glock Handgun's Slide Stop Lever.

Additionally, the Gen2 rear door extends an additional 15 degrees, making it even more convenient to insert and remove your handgun.

The interior has also been redesigned to accommodate suppressor height sights!

The front Foregrip section now also features a magazine catch to make storage and removal of your extra magazine faster and easier.

Finally, in the biggest update customers have been waiting for, the MCK Gen2 is Suppressor Friendly, and will fit suppressors up to 1.38" in diameter!

Best of all, one MCK will fit multiple Glock models! Just adjust the integrated Barrel Shroud to fit your handgun's slide/barrel length.

Currently Available For:
Glock 17/19/19X/22/23/31/32/45 — Gen 3, 4, and 5*

* NOTE: This item DOES NOT fit G22/G23 Gen 5 models or ANY 80% Frame.

NOTICE: A ruling by the U. S. Department of Justice has verified that the Stabilizer Arm on the Roni kits may legally be used as a shoulder brace. Click here to read the actual letter reversing the original ATF opinion.

NOTICE: The MCK Stabilizer is not legal for sale in California. Please consult all applicable laws in your state before purchasing.

The MCK Stabilizer is not eligible for standard discounts.
The RONI is well known worldwide as a way to turn your Glock handgun into a carbine.

This updated version of the MCK allows you to take advantage of the performance without registering the unit as a short barreled rifle.

That's right, with the Stabilizer unit there is no paperwork necessary to install and shoot your Glock in the MCK device. The MCK reduces recoil significantly and allows for much better accuracy and faster speeds. We encourage you to watch our videos for installation and shooting instruction.

Great product.


Great product. Beautiful and functional. Would’ve gave 5 stars but almost cancelled due to shipping but product came quick once shipped. This pandemic is ruining a lot but overall this product is a blast to have. I can’t put it down.

It makes range day even more fun


The MCK v2 is great. It's fun at the range, and surprisingly effective.The metal rail makes the platform great for functional improvements. Several options to select from for the base firearm, so even your brother with a 19 can use it!

Make that Glock a Giant with a few quick snapps!


Have had this conversion kit for about 8 months, I should of waited for gen 2, but the good news is the first gen is a great made item, also has lots of goodies available from my friend here Lenny. They are glad to help answer any questions. Nice pro shooting folks, They are opening a new store in Tennessee too. Also check out Lennys other Glcok parts here too, he has everything, if he doesn't have it yet he will. Shop around, see what you want and come back here to make your purchase, you will not be sorry.

Best bang for the buck !!


I have the Gen 2. I absolutely love it. Its a big hit at the range. I put a Glock 17 in mine with flip up sights and Vortex red dot. Its wicked accurate. Get the thumb rests. Its a nice add on. Just put a tactical light on it also. Going to order another one soon. So much fun and comfortable to shoot. American flag design next time. Well made also
