These are great magazines, they feed and sit perfectly in my Marui m16.
Nothing wrong with them so far, but I'd recommend not over filling them, as the feeding nub tends to lock to the bottom of the magazine, rendering it useless, unless you know how to fix it.

The work well but they sit too low in the mag chamber so you have to hold them up so they feed the bbs
