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.

    This is a true game changer! Clean lines, tight fit and smooth finish. Increase speed and accuracy down range and feels amazing in hand. Love this upgrade.

    Build quality is pretty good (better than the glock I put in it) and functions great. If you take out the aluminum shroud and grind on that housing a bit you can fit an extended barrel. A few gripes are that the part that extends to the trigger guard was a bit long and interfered with an ungloved hand, much less a gloved one. and the extra magazine well is sized for a 9mm magazine that requires a bulky/awkward adapter for 10mm. It would be nice if the 10 mag would fit without an external adapter, and for the 9mm there was an integrated insert. Also, for the brace, it would be nice if there were a latching mechanism with a button instead of the plastic hook, and if there was an option to have the brace automatically rotate open via a torsion spring. And when closed the end of the brace is kinda in the way of where you should have your finger when picking the weapon up; the brace nearly forces your finger into the trigger well and can be a safety hazard/liability .

    Fit was really tight at first but hopefully will break in a bit.

    The fit and finish were nice, tight and smooth. The instructions were clear and well illustrated. The only thing I ca see that would need to be upgraded is the charging handle. Maybe change it out to aluminum from polymer, much like it was changed on the rail.
