G&G's Redi Mag clone.
The redi mag is designed to hold an additional magazine at the magwell for fast mag changes. The G&G Ready Mag is a copy of the real steal MK I Redi-Mag.
The G&G ready mag works well as a repository for another loaded mag. I've tested with JG, MAG, G&G, and King Arms mags and it holds all of them securely. The mag release extension frees both magazines at once, making it imminently suitable for very fast mag changes. I use one on my personal rifle and can change mags more than twice as fast as anyone else on my team.
However, if you're looking for a battery box in an empty mag, I'd suggest looking at a real steal Redi-Mag MK II. In that system the mag release on the magwell will only release the mag in the magwell. In my opinion the G&G ready mag is not suitable for use as a battery box without modification.
The finish kind of took me aback when I first saw it: it's a silvery, primer grey looking affair. But it's grown on me as it works well with my OD furniture and breaks up the black receiver a bit more. The mag release extension works well, and is easy to push. The additional spring strength is minimal, and I'm happy with it's performance. The mag retention block on the ready mag, however, isn't angled, so inserting a mag into the ready mag is difficult without pushing the mag release button. I've yet to make this modification, but it's something I will be doing soon.
The right hand side sports an engraved "G&G Armament" that I was pleased to see. My GR16 is very happy with her new jewelry.
Overall, this is a must have for CQB, and a should have for woodland play. With ten minutes and a file, the only con is a plus.
Loaded mag ready to drop and slam into the magwell at a split second's notice
Gives your M4 that super-tactical goodness
Cannot insert a fresh mag in the ready mag without depressing the mag release without modification.
