OK Airsoft decided to swap their bulky HPA tank for a CO2 adapter kit on the MTW-308 to solve a rather awkward cheek weld situation. Apparently, the old tank was so wide that aiming required either a massive riser or crushing one's face into the stock, which isn't exactly the tactical look most players go for. The move to 12g CO2 cartridges provides about 100 shots per pop, which is plenty for someone who doesn't treat their airsoft gun like a garden hose.

The installation process had a brief moment of drama when a tiny plastic disc decided to act up, causing the power to drop significantly. After some light troubleshooting and a replacement part from the manufacturer, the system was back to full strength. The setup involves an expansion chamber and a buffer tube that houses the CO2, all while allowing for a much slimmer, more realistic stock that doesn't feel like you're resting your head on a log.

Operation is straightforward thanks to a magnetic cap that helps pull out empty cartridges, making swaps fast enough to perform mid-game without much fumbling. The video wraps up with some test shots showing off a flat trajectory at 90 yards, proving that you can have a comfortable face and a functional rifle at the same time. It’s a solid upgrade for those who prefer the real steel feel over carrying a scuba tank on their shoulder.
