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.

    This is a great product and will recommend it to everyone.

    This is a very impressive platform to take a very sound handgun platform to the next level. I am a retired Green Beret of 20 years active duty service, so like your CEO, am fully all about firearms and their functionality. I am impressed. The arm brace lock-up is as tight as a tank. The ergonomics of the MCK are genius. The fit of my Glock 21 SF Gen 3 is superb; nothing could be better on this device; I am wholly impressed.

    Running a 24-rd magazine in the weapon with a 13+2 magazine in the forward well, is comfortable and balanced, and the extended magazine does not at all affect portability or functionality. Thank you for marketing such a solid, well thought out masterpiece of a device to take the handgun to the next level!

    Very respectfully,

    Absolutely love this thing. Feels great in the hand and it’s really fun to shoot. I have the 45acp version and it makes my Glock 21 infinitely more valuable from a home defense weapon standpoint. Definitely recommend it.
