4x GHK AK Devilhunter Mags. One leaks, very slowly. Fussy when filling, but three of them hold gas fine. Note: have modified GHK M4 CO2 valves, hence the somewhat rough dremel job on the valves. Slight crack on one of the feedlips but doesn’t effect too much. Message me for more pictures, what you see is what you get. Only trade is Viper Tech VPmag or New Gen EB tech Stanags.
