VFC QRS 300Rds AEG Hi-Cap Magazine ( FDE )

One of the best magazines I ever used, both the high and the mid-capacity QRS mags from VFC. They feed down to the last BB (apart from the 4 ones that drop from the hop-up unit and they fit a multitude of guns. I'm using them in a G&P and a VFC Sig Sauer MCX (the one branded by Cybergun). I also used them in an Avalon Calibur CQC which I sold some time ago. No problem feeding. The only downside I see with them is that the bottom screw tends to rust. However, I didn't have any problems with them whatsoever - I highly recommend it if you're looking for stabilizing on a set of good, reliable mags for an arsenal of M4 - M15 style rifle replicas.
