Umarex T4E TX 68

Design & Build Quality

The TX 68 is built around a rugged full-metal receiver that keeps the platform solid and heavy — at 3,055g (6.7 lbs) it has the heft of a serious defensive tool. The massive muzzle brake is both functional and visually assertive. M-LOK slots on the sides of the handguard provide mounting points for lights, lasers, or other accessories. The pump-action mechanism is straightforward and reliable, with intuitive operation even under stress. A pushbutton safety is accessible and positive. The Quick-Piercing System is a standout design feature: two 12g CO₂ cartridges sit pre-loaded in the stock and are pierced instantly with a single blow, keeping the TX 68 ready for months in standby without gas loss.

Performance & Ballistics

The TX 68 (2.4746 variant) delivers energy levels under 16.0 joules — the higher-power configuration in the TX 68 lineup, suitable for law enforcement and professional security use where regulations permit. The 16-round internal tube magazine provides meaningful capacity for a pump-action platform. Each pump cycles a new round and maintains gas efficiency across the magazine. The Quick-Piercing System ensures consistent gas pressure from the first shot, avoiding the cold-shot variance common to manually-pierced CO₂ launchers. The pump-action format delivers one round per stroke, allowing deliberate, controlled fire. The full .68 cal T4E projectile ecosystem is supported, including round balls, chalk, and marking rounds.

Handling, Controls & Ergonomics

At 896mm and 3,055g, the TX 68 handles as a full-length rifle. The pump-action mechanism is smooth and positive — users report that the charging sound alone has a deterrent effect. The pushbutton safety is simple to operate under stress. The M-LOK handguard provides a stable support-hand position and mounting flexibility. The stock integrates the CO₂ cartridge housing cleanly, with a tactile and optical pressure indicator confirming readiness. The rifle balances well for two-handed use and is naturally suited to a defensive stance at home or in a fixed security position. It is not a compact platform — the TX 68 is designed for deliberate deployment rather than carry.

Ammunition Compatibility

The Umarex T4E TX 68 is chambered in .68 caliber caliber and is compatible with the following projectile types:

• T4E .68 Cal Round Ball — Standard .68 caliber round rubber ball — primary less lethal impact projectile for the TX 68.
