Umarex T4E TC68 Less Lethal Paintball Rifle Penetration Test 88 Gram CO2
Today, we are pushing the Umarex T4E TR68 .68 caliber marker to its absolute limits.
If you watched our previous testing, you know we already ran the Umarex T4E TR68 using the dual 12g CO2 adapters. However, those cylinders had been sitting in the launcher for a while and likely leaked, meaning we didn't get a true reading on maximum power.
Not today. We are locked, loaded, and puncturing a brand-new, 88-gram CO2 cylinder to give this marker a full-jam performance review. Our ammo of choice? High-impact, .68 caliber nylon plastic balls weighing just under 3 grams each. Combined with this massive CO2 tank, we are pushing a hard-hitting 30 Joules of energy.
Let's see what happens when residual heat meets heavy-duty targets.
Target 1: The 3-Ply Plywood Test
We started out in semi-automatic mode to see what a couple of precision shots would do to standard 3-ply construction plywood.
Shot 1: The first impact did some good damage almost making it clean through the plywood but the CO2 had not just yet settled in.
Shot 2: A follow-up shot confirmed the devastation, easily tearing a clean hole through the wood now that the CO2 was fully primed.
The Verdict: The TR68 backed by an 88g tank makes absolute mockery of standard plywood. If you are looking for pure penetrative power, semi-auto maximizes your velocity because the CO2 doesn't cool down too rapidly between pulls.
Target 2: The Galvanized Steel Challenge
Next up, we raised the stakes with a heavy-duty galvanized steel trash can lid. Steel is notoriously unforgiving, but the TR68 didn't bounce off.
Pumping a round directly into the steel resulted in an immediate, loud puncture. We put a hole straight through galvanized steel. The raw kinetic transfer didn't just dent the metal; it ripped clean through it.
Target 3: The Plastic Bucket Lid
I also wanted to see how the Umarex T4E TR68 handled a lighter, more flexible polymer target, so we lined up a shot against a standard plastic garbage can lid.
Even with the flexibility of the plastic absorbing some of the impact, the marker didn't hesitate. Idid not get a super clean shot adn hit the lid on the outer edge, The .68 caliber nylon ball punched a clean, definitive hole right through the plastic lid. It proved immediately that thin plastic barriers offer absolutely zero protection against this setup.
Going Hot: Full-Auto Mag Dump
To wrap up the torture test, we set the plywood back as a backstop. We flipped the selector switch over to full-automatic to see how the marker manages multiple full auto bursts of the remaining rounds in the magazine (the magazine holds 20 rounds total so about 15 rounds were left).
We let loose a few intense bursts to empty the mag and the damage was definitive! In full auto the cooling effect of the CO2 is noticeable lowering the power output of each round, even so I would not want to be anywhere near the line of fire when 20 rounds or .68 caliber nylon balls are heading your way. I may not of penetrate the 3 ply wood this time but if it was skin that would be a different story.
Less-Lethal Defense & Deterrent Capability
Looking at these results, this setup functions as an incredibly formidable less-lethal option.
If someone is coming at you, a rapid-fire barrage of 3-gram nylon balls at 30 Joules is going to absolutely slow them down. It serves as an exceptional, painful deterrent. While it is explicitly less-lethal and won't cause critical injuries under normal operation (assuming you are smart and avoid the face/eyes at close range), the sheer impact force will ensure an intruder doesn't stick around.
For maximum velocity against heavy clothing (like a thick winter parka), stick to semi-auto to keep your pressure peaked. For absolute suppression and stopping power, the full-auto capability is there to get the job done.
