These are custom made 150 round AK magazines with the shells of a real steel Romanian 7.62 magazines and G&P 150 round mid-capacity internals. These magazines have been built due to the lack of tough magazines that can handle how I choose to treat my magazines in game play, which is very rough. Mostly dropping mags as I do quick reloads via knocking the mag out with the wack of the new mag. All have been Tested in E&L, LCT and Real Sword AEG’s with perfect performance. Note; These have a very realistic sound, feel, and snap, and hold in all 3 of my Real Swords T56’s, E&L (gen. 1 & 2), and feed flawlessly with high RoF All can be disassembled for regular maintenance.
