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.

    I love it. I had to refer to the you tube video to get the glock seated right. After watching the video… worked like a charm

    So Far, So Good! Once I finally figured out the trick to seating the Glock 20 properly into the MCK, It has been great. So much more accurate to shoot with a stabilizer! speaker of the stabilizer…. The gen2 extended stabilizer is GREAT! Some reviews said it was too flexible, but mine is nice and firm with no bend… Awesome! Added the red dot onto the rail, and this thing is an accurate weapon! Also added the thumb attachments, and trust me they are worth the money! Makes for a very comfortable hold. Now just to put hundreds of rounds through the MCK and see how the reliability holds up.

    Pain to put together sometimes . Its gotta be just perfect to go together but works great once guns in it

    Got my MCK faster than I thought I would and I couldn’t be more happy with it! It feels amazing and matched my glock perfectly! Can’t wait to take it to the range and break her in.

    I’m impressed with the MCK it’s amazing what it does to a pistol.

    It’s gives me the feel of a submachine gun. Only thing it’s not. It’s a Glock in a conversion kit. Also, it’s lite weight. Which I like very much. Overall, good piece of gear!

    Love it. I bought 2 for my G45’s and 2 for my G21’s So now I have 4.

    I couldn’t find a 10mm PCC, so I decided to go this route so I could take further advantage of a truly great caliber. The kit works great, once I figured out the trick to fully seat the pistol into the housing. It’s amazing how accurate this makes a simple pistol. It’s a great. I highly recommend the Gen 2 extended stabilizer and the thumb rest.

    To be honest and up front, my ranges are closed so I have not fired with this kit installed as of yet. With that said this seems to be built rock solid and would tame +p rounds like bbs. With a base cost of 200 bucks, it transformed my g21 in a poor mans mini Carbine. No need to spend a grand on a Kriss or 800 on a Scorpian this does the trick and looks just as fantastic. I’m thinking of buying another Glock just so I can purchase another MCK. Customer service on the website was fantastic and shipping speed was phenomenal!

    This is a great piece of equipment for my glock. Looks and feels great. The customer service is A++. Had an issue, 1 email later it was cleared up and fast. Will buy again
