The next generation of Micro Roni is here! We improved our past generation models into the ultimate conversion kit. Micro Roni Generation 4, we call it Micro Conversion Kit, or simply MCK and it’s 100% made in the USA.

This Micro Conversion Kit fits multiple handgun models, into one platform, and helps convert your pistol into the ultimate submachine gun.

It is significantly improved from previous generations of the Micro Roni Stabilizer. Available for select Gen 3, 4, and 5 Glock models.

 

This Micro Conversion Kit is a lightweight and sturdy platform for Glock handguns. It has a barrel shroud made of aluminum with a polymer body. The extended stabilizer, which now comes standard, enables one-handed firing for better shooting performance. It also comes with a Velcro® strap fastener which provides a custom fit to any user. MCK is the most cost effective conversion kit in the world. Fastest assembly/disassembly conversion kit on the market. Improving accuracy dramatically up to 200 yards. We are the exclusive licensee of the SB tactical stabilizer brace for the handgun conversion kits.

    After working the stiffness out, the 21 fits like a glove. And, the MCk makes for a solid support. In a “situation” there is just more to hold, and I like it. Thanks.

    I think this will be great. Still waiting for my G21SF to arrive. Will give you a buzz once i put my hands on it in the range…

    I am extremely happy with my decision to pick up the MCK. I had initially bought the G19 compatible version for my wife to utilize as part of her home defense kit. I was so taken by it that I had to have one of my own for my G21. These kits are a great investment for anyone interested in maximizing their home defense capabilities.

    Managed to makea short trip to an isolated piece of desert in order to test fire the mck. Worked A-OK. Now have a house armanent for these uncertant times. Great product which gives an 80 year old man a great family protection tool.

    Reside in El Paso, TX and upon delivery of the MCK our fair city’s mayor ordered a corvona virus stay at home order. So have not been able to shoot the mck. However, I realized that the Glock 21s trigger is uncovered and felt this was not a safe carry in condition 1. My humble solution was to purchase a Glock trigger plug and use it in order to safely carry the MCK inside a backpack. As soon as this crazy virus has finally ended I look forward to testing this MCK. Just my two cents worth of information.

    This conversion kit is a blast, and is a great way to repurpose your glock (or other pistol). This kit is a must have for the range and as a handy night stand alternative.
