Umarex T4E HDX 68

The Umarex T4E HDX 68 is a .68 caliber pump-action CO2 shotgun platform. Unlike pistol-format launchers, the HDX 68 fires three projectiles simultaneously per shot, delivering a shotgun-pattern impact spread. It is widely used by law enforcement and security professionals for its psychological deterrence and area-effect capability.

Design & Build Quality

The HDX 68 uses a full-length pump-action stock with an 88g CO2 reservoir in the grip area. The three-ball magazine feeds horizontally; each pump loads a fresh 3-ball payload and advances the CO2 system. Build quality is primarily polymer with steel internals. An under-barrel Picatinny rail accepts lights and accessories. The platform ships in orange/black and all-black configurations depending on market.

Performance & Ballistics

Each trigger pull releases three .68 cal rubber balls in a spread pattern. At close range this delivers significant impact force across a wider area than single-projectile platforms. Effective range is shorter than carbine-format launchers due to the multi-ball spread pattern and short barrel. The 88g CO2 tank provides significantly more consistent shot-to-shot power than 12g cartridges in cold conditions. Shot count per 88g cartridge varies by temperature and valve adjustment.

Known Issues & Limitations

Very short effective range compared to rifle-format launchers
Three-ball payload limits area selection — elevated bystander risk in confined spaces
Slower follow-up shots than semi-auto platforms
Larger and heavier than pistol-format alternatives
88g CO2 sourcing can be difficult in some regions

Accessories & Upgrade Ecosystem

88g CO2 adapters and spare tanks
Picatinny light and laser mounts
.68 cal rubber ball and washable paintball ammunition
Sling attachments for two-point carry

Platform Summary

The HDX 68 fills a specific niche: area-effect deterrence at close range. Its three-ball payload per shot and shotgun form factor create a psychological and physical deterrent profile that single-projectile launchers cannot match. For room-clearing scenarios, close-range perimeter work, and situations requiring wider coverage, the HDX 68 is a strong choice. Its range limitations and slower follow-up fire mean it is best paired with other platforms in extended engagements.
