So, I made a stupid mistake and traded my flash mags for six mid caps. Now, normally, that'd be fine but stupid me didn't take my AEG with me when I traded. Turns out, the mags won't fit. The magazine catch won't catch. The guy owned, if I remember correctly, a combat machine and said the mags were metal STAR 90rnds. I own an E1 stag arms m4 plastic body. Anyone know specifically why these won't work with mine, and what brand will? Or, is there any way to rig them to make them work? Any help would be greatly appreciated, thanks!
