ARES AMAG 170rd Magazine M4 / M16 Mid Cap Magazine for AEG Rifles (Color: Dark Earth)

"This mag pushin P for real

"These mags are phenomenal!
I bought them for my krytac LVOA and they fed every bb and there was no fitment issues!
The only major problem about these mags was they only hold 160 .32g bbs instead of 170 as advertised.

Pros:
Good build quality
Very durable
Good feeding

Cons:
10 bbs off advertised capacity
length of the mags (depending on personal preference)

"the only problem I have with this product is two of my five mags won't feed. When opened they both had pieces of plastic broken inside and now keep on staying compressed and won't feed, but my other three mags work just fine.

"Eye-catching for sure but after less than half a year of use the springs on these just collapse or something when I fill them up for a game. Not sure exactly what happens inside but bb's will not feed and rattle around inside loosely like a hi-cap. Upon opening up the mag (which is admittedly very easy) the spring is compressed but it seems to catch itself on one of the curves inside the feeding track. Probably something that can be remedied with a high quality mag spring (which again is very easy to change out), but I'm guessing the issue has more to do with the actual shape/pathing of the feed tube in which the spring resides. 170 rds is already not very impressive for a mag this large, but if even trying to fill the mag to capacity breaks it, I'm not sure I can recommend these guys.

TLDR; cool-looking, but the springs get stuck and you should probably replace them with better ones.
