Constructed of high-impact polymer and TPE rubber—lighter and more durable than conventional rubber. Fires folded and locked. Compatible with Gen 1 & 2 MCKs; secures via Velcro arm strap. Exclusively licensed to CAA USA by SB Tactical (patent owner)—the only authorized MCK brace kit. Non NFA item.
The MCKGEN2 Stock is the NFA rifle stock exclusive to the MCKGEN2 platform. Designed to shoulder while firing, it delivers optimal comfort, ergonomics, stability, and accuracy. Note: Installing a stock converts a pistol into a Short-Barreled Rifle (SBR), requiring ATF/NFA compliance.
The Stabilizer Brace is the short replacement stock for both MCK and Micro RONI® platforms. It enables one-handed firing with a custom-fit hook-and-loop fastener and adjustable nylon brace. Features a folding mechanism for stability and includes a forearm strap for single-handed support—without converting your handgun into an SBR. Designed mainly for the US market.
The TAC Kit transforms your Micro Conversion Kit into a compact setup with a One-Point Sling (Push Button Swivel) and thumb rests, inspired by HK MP5K dynamics. Full arm extension plus bungee resistance creates a steady platform for better accuracy and control. Includes a forearm strap for single-handed support without converting your handgun into an SBR.

I already had the Gen 1 for my Glock 20/21 (I utilize the system for my Glock 20). I love the increased capability with having an actual magazine retention/release button, compared to just relying on friction to work and gravity NOT to work with every shot fired from my system. I also love the rigidity in the brace on this system, versus the Gen one which is just rubber, even though I did love how it would just eat the recoil. Absolutely LOVE IT!!!!
Love my gen 2 mck…didn’t take long at all for shipping!
It is absolutely beautiful it works like a charm
Haven’t tested it yet but looks well made
I love the MCk I like how it works mechanically put it in my Glock 21 it’s pretty easy. The only thing I didn’t like too much was the mag holder when I put in the mag holder it seems to be a little loose doesn’t fit like nice and snug so it seems to be some play. Besides that it shoots great it’s pretty accurate and I still didn’t even put on my sites works good I bought generation two and generation one I’m happy with it
