"Overall these are really good mags, ive had them for about a month and had only minimal problems, i dont know if this is my gun or mag but my gun keeps double, if not triple, firing, only with .20 bbs though, and after realizing my mag pouch is a double stack i plan on buying many more.......as sooon as they come back in stock that is. P.S. i use these in my AGM Full metal M16A4- very little, if any, wobble."
