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.

Got the gen 2 for my P365xl and just wow. This thing is amazing and fits right in my vertx everyday carry back pack when folded with scope, flashlight on the side rail and thumb rest on the other all attached without taking anything off. Took to the range and this thing makes you laser accurate with almost zero recoil. Would buy 100x over!
Great company to work with, fantastic customer service and excellent quality of products
Quick shipping, took to the range as soon as I got it and I love it!!
Mike: I an old guy who has had polio since I was a few months old. My left hand and arm do not bend well. I mention this only so you understand my next statement. Your redesigned front grip is the first time in a lifetime of shooting that I have been able to wrap my left hand around a barrel without modification. Thank you! Needless to say, I love the kit.
