Based On What You Pick
1st Responders Discounts© 2026 RIGHTS RESERVED CAA USA LLC // Meta Tactical LLC // Proudly Designed, Developed & Made in the USA By Plastimold Products LLC
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.

Everything was as described, love my new weapon.
I love this. It is compact and so much fun to shoot.
Very happy with this kit I threw everything at it I could mud, water, grass, sand, throwing it around on the ground it’s still tight and intact I’m impressed.
Excelent
I love your MCK for my canik. It’s best investment I made as far as I’m concerned. I highly recommend. I still need a sling,and really want the 3 gen stock.
