The GBB Enthusiast tests the gas efficiency of the Tokyo Marui Gas Blowback Rifle in semi and full auto modes... "Unfortunately, I have only 1 mag since they’re sold out everywhere and I’m only able to test the mag that came with the gun.

For the final results, the mag that was shot in the semi auto mode, shot 179 rounds and in full auto, 124 rounds. Each mag is capable of holding 35 rounds and that is equivalent to a bit more than 5 mags worth of BBs on semi and around 3 and a half mags worth on Full auto.

Personally gas efficiency doesn’t matter too much to me because I top up my mags every time I use them but it was definitely interesting to see how many rounds the TM AKM could go through. Overall, I’m extremely impressed by the gas efficiency."
