Golden Eagle 30 Round Magazine for Hi-CAPA Gas Blowback Airsoft Pistols

"This mag worked very well for my needs. I have a JAG Arms GM5 5.1 Gas Blowback Airsoft Pistol and this mag is an exact replica of the one the gun comes with. So it works very well with my platform. Holds gas well and was able to fire 2-3 full mags with one fill. The last mag had a little less power but that is expected. Happy Airsofting!

"Great working mag but I have the same issue as many others in that there is a missing o-ring around the filler valve so it doesn't make a great seal when filling

"Great mags, they fit my double bell 5.1 hi capa, but my only problem is that they came with no O rings on the fill valve ( where you put the gas in), so I had to purchase O rings (3mm OD 1mmID 1mm width ) separate so the mags can fill without spilling gas

"Im gonna start off by saying this, if they kept gas, they'd be amazing. I've gone through 3 of them, all of them get the same problem, they wont fill. I've tried looking for new valves, I haven't found any. When they did fill, they worked amazing, but they don't work anymore.
