6mmProShop Co2 Magazine for Umarex/KWA MP7 Gas Powered Airsoft SMG

"Good magazine, every bb shoots and the bolt still locks back. I had an older model Mp7 and had to shave a bit off the bottom of the grip to get the magazines to fit. Other than that they are great, still 5 stars.

"I bought 2 of these things for my KWA MP7 and I'm very pleased.
My older mags had had problems where the weapon wasn't locking back after the last round but as soon as i threw these in the MP7, it was snappy and it was locking back after the last round. Ill be buying another mag here shortly

"These mags are AMAZING. for somebody that lives up north, these are a god send. When we would play outdoors in 40 degree temps, my MP7 wouldn't function to it's full potential. I pick up a couple of these when they were on sale. They are a bit more heavy than the green gas variants. This led to a problem, the mag catch on my MP7 couldn't support its weight. Other than that these are great.

"This CO2 Mag is the Mag i been waiting for a long long time, one CO2 bulb can shoot all 38 rounds of BB, I tried the 025 BB and is quick satisfy with it, next test is the .030 BB. see if it can outshoot the UZI from Tai Wan?

"They shoot a bit harder than the green gas mags from Umarex and are more consistent in cold weather.

Downside is that they’re 25% heavier, bottom mag cover is prone to breaking if the magazine is dropped, and the magazine started leaking gas after _10 games of usage

"got two of these in a package deal with the kwa mp7 and both magazines failed horribly. i now need to buy a gas valve key to possibly correct the issue. if not im sending the mags back and hopefuly ill recieve magazines that arent bunk on arrival.
