The MCK 1.0 Micro Conversion Kit. For Glock® 17, 19, 19X, 22, 23, 25, 31, 32, and 45. Whew.

It's here, folks: The next version of the famous Micro Roni. Loved by GLOCK (and P80) owners everywhere, the available MCK Roni and other Micro Conversion Kits you'll find available here are 100% made in the USA. Providing a lightweight, sturdy platform for GLOCK and P80 handguns, the Roni provides stability and accuracy for all shooters thanks to its included stabilizing brace. It's perfect for disabled shooters or those who require extra stability and long-range accuracy out of a traditionally close-range handgun platform.

What Are MCK and Roni Conversion Kits, Exactly?

Think of these GLOCK conversion kits as drop-in stabilizing braces coupled with an exoskeleton. All conversion kits are made from high-density, weapons-grade polymer that sports a similar look, feel, and durable finish to GLOCK and P80 handgun frames. Throw in the included barrel shroud, and you've got an aesthetic, highly functional conversion kit with a Picatinny rail, available optics and light mounts, and additional storage capacity for extra magazines right next to the mag well itself.

  • Easy drop-in, fast mag changes, better accuracy. Win-win.
  • Compatible with Gen 3, Gen 4, and Gen 5 GLOCK models.

Easily Mount Irons, Back-up Sights & Optics

You know you've always wanted to try out your favorite GLOCK or P80 with a reflex sight. But what if you could throw on carbine-style iron sights and truly dial in your blowback shooter for some impressive range and performance? That's just one reason why shooters love kits like the Roni. Sporting a standard M1913/Picatinny rail, you'll find it's easy installing virtually any optic you want - even a magnified scope.
