I've had this magazine with my G&G Soc 16 for a little under a year.... about 8 months I think, and its performed perfectly. It's leagues better than the CA M14 magazine.
-Finish looks great- it's grey, not like the toyish black finish of the CA magazine.
-Feeds very well- the CA magazine has jammed at almost every game I've used it in at least once, sometimes twice.
-It's a good fit in the magazine well- you have to use a little force the first few times you put the magazine in, but it loosens up just a little bit eventually, and it doesn't wobble at all.... which the CA magazine does.. badly.
-Holds 470 rounds- I don't see myself paying just as much for an 80 round midcap when the G&G M14 will rip through that in just under 5 seconds on an 8.4v.
Don't settle for the cheaper CA magazines, these are much better, and seem to have any kinks worked out that previous reviews have mentioned.
