RAM Rifle Umarex T4E TC 68 7.5J Semi-Auto

Umarex TC 68 (also Tactical Carbine) caught our attention already at the IWA 2025 trade fair in Nuremberg. It is a multi-purpose CO2 rifle which, depending on the chosen power version, can be used for self-defence, backyard training shooting, or for paintball matches.

POWER

The TC68 rifle is available in 7.5 J, 16 J and 40 J versions.

In the 7.5 J version it offers only semi-automatic (semi-auto) fire mode, where you have to pull the trigger for each shot.

The 16 J and 40 J versions offer a fully automatic (full-auto) fire mode and of course also semi-auto mode.

AMMUNITION

For ammunition you can use practically any rubber, paintball or pepper .68 calibre projectiles (17.27 mm). The lower 20-round magazine is even compatible with non-round “precision” type projectiles for better accuracy.

If you require a higher ammunition capacity, you can use the supplied adapter for mounting any paintball hopper-type magazine. A lower “dummy mag” magazine plug is also included in the package.

POWER SOURCE

This rifle is powered by a large 88 g CO2 cartridge, which is screwed into the rear part of the main block after removing the stock. The manufacturer states that one cartridge is enough for 250 full-value shots in the 7.5 J version, 180 shots in the 16 J version and 80 shots in the 40 J version. You can also use an adapter for 2x 12 g CO2 cartridges, which does reduce the power and number of shots, but offers the popular quick-activation system by striking the rear of the stock. A red indicator that pops out of the top of the stock when the system is pressurised informs you that the power unit is active.

However, if you want to maximise power and shot count, you can convert the rifle into a PCP air rifle by installing any 200 cc HPA bottle with regulator (with an output pressure in the range from 800 up to a maximum of 1200 psi / 55 to 82 bar). Umarex offers a set with adapter and polymer buttpad as an optional accessory.

A welcome innovation from the manufacturer is the safety valve located in front of the stock. It allows you to safely depressurise the internal system of the gun while the cartridge remains pressurised. Although we still do not recommend leaving an activated CO2 cartridge in longer than necessary (freezing carbon dioxide may eventually damage the valve O-rings), the valve is very handy for maintenance or short breaks during shooting. And if instead of CO2 capsules you use the above-mentioned HPA bottle, there is no risk of seal damage caused by freezing gas.

The second new feature is the power regulator located behind the pistol grip, allowing you to regulate the gas flow from the cartridge into the gun. This lets you set the gun’s power for different purposes – for example, reduce the power when you are going to a paintball match, or increase it in case of self-defence. The regulator cover also serves as a tool for turning it.

CONSTRUCTION

The 300 mm barrel of the rifle is mounted only on its own Autococker thread, so it can be easily removed for cleaning or replaced with a tuning barrel. At the end with M22x1.5 thread there is a metal imitation muzzle brake, which you can, for example, replace with the tracer device Umarex T4E X-Tracer .68.

The entire TC 68 rifle is based on the AR-15 platform, so you will find lots of standardised components such as an easily replaceable AR-15 grip, an upper Picatinny rail, a handguard with multiple M-LOK slots on the sides and bottom, an ambidextrous fire selector, ambidextrous magazine release, and ambidextrous QD sling attachment point.

The internal frame of the rifle is of course made of metal and then covered with a lightweight impact-resistant polymer body. As a result, the TC 68 boasts a durable construction while keeping the overall weight at just 2900 grams.

Maintenance

Since the gun is powered by CO2 cartridges, the rubber seals may, over time, become brittle and crack due to freezing carbon dioxide. You can prevent this by occasionally applying a few drops of silicone oil to the neck of the inserted cartridge. At the same time, we do not recommend leaving an activated cartridge in the gun longer than necessary. If you know you will not be shooting for a while, release the pressure and remove the empty cartridge. This is not necessary when using an HPA system with compressed air.

Our opinion: The TC 68 tactical carbine is the most impressive RAM gun we have had here so far. It offers endless possibilities of use, adjustable power, and you can use different power systems. In addition, thanks to the AR-15 platform you can mount practically any commonly available accessory. Umarex has really outdone itself this time and from Balistas it gets a thumbs up.
