"This magazine is perfectly identical to the mags that came with my matrix/S&T rifle. Has worked great and I have skirmished it multiple times. Just the restock is annoying, but that’s evike’s fault not S&T

"nice magazines, but Ive been having troubles feeding BBS into them with a speed-loader, and cannot find a gbbr mag loading tool that works at all for it. other than that it works very well with this m4 :

oh also the ones i bought did not come with the fill valve o-rings, or they were really dry so you might have to buy your own.

"Recieved My GBB today, I bought an extra magazine with it. Neither mag will hold the gas. I can get about 20 rounds through them before they flake off and one of them looks used. The mag cannot provide full auto burst. It flakes off even faster. This doesnt reflect on the GBB it self. I think the quality is great but the mags REALLY SUCK!!
I will need to call envike to see what solution that they can offer. This is no good if I can only get 20 rounds through it.
