The UNIT4 Training Rifle is a mil-spec, standalone, M4 training system that uses CO2 to fire 8mm non-lethal projectiles. Classified by the ATF as a non-firearm, the UNIT4 is magazine fed and utilizes UNIT Solutions' proprietary TPAK cartridge system to deliver non-lethal projectiles from the magazine to the training rifle.

The UNIT4 Magazine has been specifically engineered to maximize operator safety and increase durability for rugged training. Crafted from robust materials selected for maximum durability and featuring a carabiner style latch to provide maximum protection, the UNIT4 Magazine is ONLY compatible with the UNIT4 Training Rifle and UNIT4 TPAK Cartridges.

The UNIT Solutions patented TPAK is a low cost, preloaded cartridge containing 30 8mm marking or non-marking projectiles and CO2 propellant. The non-lethal projectiles are 100% biodegradable, lead-free, brass-free, do not contain a primer, and will not penetrate covered human skin. TPAK cartridges are only compatible with the UNIT4 Training Rifle and UNIT4 Magazines.
