"these work great in my high rof set up for my m4, they feed perfectly and one wind last for quite a while. also if you use an under barrel m203 these stick out a little longer and make mag changes easier.

the only con i can think of is that these don't fit as well in the Alice style pouches as other magazines (2 instead of 3) but for the vast majority of people this is a non issue.

"Just received it in the mail

Price ($13) per round (500)
Fairly solid build quality
Wolf grey looks pretty cool (doesn't fit too well with my tan rifle though)
Actually kind of light. It weighs the same full as a 400rd G&G mag. (could be pro or con)
Really easy and good feeling wind.

It's build seems a little cheaper than my G&G hi-cap
Noticeably bigger than a regular m4 hi-cap (could be pro as well but for me it was a con)

Overall for $13, pick this up if you need a hi-cap (especially a 500rd)

"I currently have 15+ of these mags. They are Ok for the 13 bucks you pay.

Lots of BBs 450 500 rounds
Cheap price 13 each
Fit well in Most of my M4s my KWA Cqr is a tite fit. Fits my G&Gs. fits well and other M4 rifles I have.
Feed good
The plastic trap door is kind of cheap feeling be gentle on the mag.
The paint Falls off in the box...The 1st insert of the mag and you have to blow out the mag well of paint flakes... The paint Hurts this mag badly.. I mean a scratch is one thing but this paint you can blow on the mag and it flys off... Im considering just a light sand on all 15 of these I own....Lots of work....
The mag is Great for the price but dont expect to much.. If you want high quality mag pay the High quality price.. These work well and you get what you pay $13.
5 Stars if NOT for the Insanely poor paint/coating what ever you want to call it.
