||These mags are very nice, but had a few problems with them and my gun. 1: i had to give a little extra push to get the mags to catch which isnt a biggie 2: i had to file down the bb stopper ( the thing that stops the bbs from coming out when the mag isn't in the gun) to make the mags feed properly. But other than that the mags are durable as anything, have a good weight for being plastic, have nice capacity, and feed well once i modded them.
Tough as Nails (probably one of the hardest plastics ive touched, i kid you not)
Nice Capacity IMO
Have a good weight for being plastic (and not weighted)
Feed well (once modded)
Clip to each other
A little extra force to get the mag to catch
had to mod the bb stopper for proper feeding
(those two could have just because of the brand i have)
dont clip to original mag
dark, so it's tough to see rounds left
All in all once i modded them, great mags, i feel theyll last me years of combat
Other brands may not need modification to the bb stopper, and may catch more easily (i have a plastic gearbox softair sig 552) and i recommend these mags to anyone looking for mid caps for their sig!
