KSC Green Gas Magazine for VZ-61 Scorpion Gas Airsoft SMG (Model: 40 Round Extended)

"I purchased one of these (along with two KSC long magazines) to use with a KWA VZ.61 Scorpion because the KWA magazines were all out of stock at the time of purchasing it. I knew that KSC magazines were compatible with the KWA Scorpion, as the KWA Scorpion is a clone of the KSC version. However, I did not expect the KSC magazines to perform the way they do. For whatever reason, the KSC magazines not only fit perfectly and fire, but the recoil is WAY harder and the report of firing is much louder. The best part though is the HUGE velocity increase over the KWA magazine (the only one that was included with the gun). The KWA VZ.61 Scorpion fires at approximately 240-250 FPS with 0.2g 6mm BBs using the included short magazine, but with the KSC magazines, it fires 290-300 FPS! That is a 40-50 FPS boost just for using a different magazine! That along with the extra recoil and sound makes these a massive upgrade for the KWA Scorpion in general. The long and short magazines both do this, so it is not just from the larger size, it is definitely because of the KSC make. The only downside is the gas efficiency, which is quite a bit lower. You can still blast off a fully loaded long magazine in one trigger pull on full auto, but that's it. It's almost out of gas after that. Semi auto gives you about a mag and a half, so like 60 rounds on the large magazines and 40 on the short ones. I do not have a long KWA magazine to compare to, as the magazine sizes have different gas capacity, but the short KWA magazine gets 50% more shots on a gas charge. Obviously the KSC magazines are putting out more gas, probably because they were designed to use HFC134a (duster) gas instead of green gas. Regardless, these KSC magazines work fantastic with my KWA Scorpion and I highly recommend them to anyone owning that gun.
