The updated Micro Conversion Kit Gen2 for your 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.

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.
