I've been doing some thinkin and was seriously considering standard capacity mags for my M15A4 for the realism factor. I have a S&W MP15 that has almost all the same parts as my CA M15A4 AEG and was considering using my airsoft rifle as a REAL training rifle. Does anyone have any suggestions for the Standard Capacity mags??? I'm really thinking MAGPUL PMAGs for it because I have 1 already and 5 more on the way for my AR. Opinions?? Suggestions??? Any and all are appreciated.
