88g CO2 cartridge stock kit HDR 68
Transform your Umarex T4E HDR .68 revolver into a high-capacity tactical carbine with the Tactical 88g CO2 Cartridge & Stock System. Designed to bridge the gap between heavy-hitting power and shoulder-braced stability, this modular buttstock kit houses a large 88g / 90g CO2 cylinder directly inside the stock assembly to drastically increase your shot count per air fill.
Available now at Elite Shooter Supply, this system replaces the standard 12g CO2 quick-puncture setup with a high-volume adapter housing. By shifting to an 88g CO2 capsule integrated into an adjustable tactical buttstock, shooters gain up to 4x to 5x more shots per capsule, eliminating constant CO2 canister swaps during extended range sessions or tactical training drills.
Engineered with high-strength composite polymer and anodized aluminum components, the stock provides three points of contact for rock-solid stability, reduced felt recoil movement, and faster follow-up target acquisition.
