The Kuroneko YZ Toy Gun Channel converts the SRC M92F GBB to be able to use CO2 properly... "Let's easily convert the Beretta M92F type toy gun, which was 8,980 yen, which is too cheap on Amazon, into a CO2 gas gun! The CO2 magazine for Baton's BM9 can be used as it is, but the initial velocity is not so good... I will adjust the initial velocity so that I can use it with confidence. The point is detune."
