MCK Gen4 stabilizer is the best conversion kit ever
by Michael Mata
I ordered mine directly from CAA, haven't been to the range yet but I'm sure it wont disappoint. Better then the last version. Hope they'll be coming out with some new muzzle shrouds and breachers for this model like there standard SBR version does.
Got this from the Glock Store and works great on my G17G4 and G19G5. I had to take my medium back straps off to get the weapons locked in the MCK-the locking tab will not engage. Taking the guns off was challenging as it was a tight fit. Its easier when I push the gun fwd then engage the release tabs and pulled back. Pay attention when installing the gun-you have to push it straight forward otherwise it will catch the sides of the channel. you’ll notice this right away when the gun jams as you push it forward while installing.
Great Accessory For Your Weapon!
Put my 19X in and I couldn’t believe how accurate this is with the Sig Romeo 5! This thing ran with No problems. Used a 50 round drum and it is the most fun I’ve had with Weapon in a Long time!! You have to have one!!
GIMMICK? NO Way!

This is the real deal! Looks Great and shoots like a dream! This MCK is awesome can't say enough good things about it. Shot 200rds. though it with my G19 Gen4 it functioned flawless and accurate. Made the steel plates dance and sing. Used a red dot on it, shot faster & more accurate than ever. It will make you look like a pro. It's the perfect combination and loads of fun! Get while you can. Support the NRA.
It will fit the P80 frame with some gentle Dremel work.
Just received my MCK for a G19 built from a poly80 kit with a custom Rock fluted slide and threaded barrel. When ordering I was concerned whether the extra half inch of the threaded barrel would fit when the barrel shroud was extended to G17 length.
Barrel was fine, but the P80 trigger guard was a mm too wide on each side to fit into the unit. Some gentle Dremel work on the flared lower portion of the P80 guard and some bits of the MCK, and loosening the screws holding the two halves solved that. Then I saw the Rock slide had only 5 serration grooves while the MCK was designed for 6, so the extra tongue made the captured bolt of the MCK bulge slightly.
Lube and repeated working of the MCK charging handle after loosening the screws got the action sliding smoothly. Have not yet had an opportunity to test fire it, but it seems to be a good, if tight, fit.
Bottom line: works with the 940C frame if you are willing to do a bit of careful Dremel milling of the frame and the MCK.
MCK comparison with Micro-Ronni
by Renny Schoen
MCK Micro Conversion Kit is vast improvement over Micro Ronni which I also have. and it cost about half what I paid.. It does everything the Micro Ronni did only a lot better with no hangups and issues. The white light from the Ronni works on the MCK. Everything on Micr-Ronni is transferable to MCK. Micro-Ronni only adapts to one specific pistol, where as the MCK adapts to a whole family of pistols, like Glock. The weak side hand placement works without a special thumb rest. Thumb rest from Ronni works on MCK if you want. Shoulder strap attaches on either. No pistol brace extension needed. MCK uses pistol's slide release so no mal-functions like Ronni. The only thing the Ronni has that the MCK doesn't is a trigger guard flap which many users did not like anyway.. The MCK cost half of what I paid for Ronni and accessories.
Fantastic addition for any shooter..
Excellent conversion kit to extend your G19 out to 100M with ease. Light. compact. well-built, and so very easy to install your Glock. I highly recommend some extended mags as you will love running all the ammo you can. I also recommend the upgrade kit with light, thumb guards and sling. Even the wife likes getting her hands on this one at the range.
I love the MCK but the red color is off a bit and not like the picture. People ask me if its pink and I say no it's supposed to be red. I have the red extended controls in red and they dont match the MCK at all. If you want red, I'd buy it at the store and not order online. The device works great but the color is the only thing I'm disappointed at
Ordered the MCK from GlockStore. Came in a week later. I also ordered a 50 round drum mag at the same time. Both products came brand new in box, shipping was fast a easy. I will be using Glock store again, and recommend to all. Thanks guys!!
Get this if you want to knock out the red center!
I tired this on my G17...wow!....Knocked the ten ring out nearly everytime at 30 feet. Used a red dot and/or a bull green dot laser....piece of cake! What a difference the additional points of contact make to stabilize the weapon.
Got it today looks a feels great can’t wait to get out to the ranch a put some lead down range
Good PDW for the price.
The only real problem I have had with the MCK is that the plastic pin on the lock gate broke. I fixed it with a steel roll pin. Otherwise, it has been really fun to shoot with.
I built a Polymer80 G19 specifically to keep in the MCK. There is a little machining to do on the Polymer80 lower to make it fit, but it's simple to do. Also added 2 ETS 30rd mags to increase the fun time.
