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.

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.
