Yeah the star are pretty good. I've got 2x vanaras 100round 2x 100round MAG mags 10xstar 30round mags 2xg&p metal 100round mags and a jg hi-cap for my TM mp5a2. all of the plastic mags require a little filing or sanding to catch easily. the metal ones click in without any problems. But all of them feed without any problems.
