Guys, I am so angry that everybody thinks it's forum time and asks questions about the product. Please Stop!!! I would say more if there werent any rules to this thing.
These mags are pretty good. I got a couple for my m4 and the feed well. It does take a few times of using it and a little silicoln to get it to feed well though. these are sturdy enough plastic that I feel comfortable throwing them to someone who is out of ammo. These are not the best mags in the world. since they are cheap mag brand, they do not have as much quality as a G&G mag or any other metal mag.
pros:
sturdy platic
decent capacity for mid cap
really good price (50/8= about 6$ a mag)
light weight(wont weigh down your rig)
feeds well
cons: takes some effort to break it in
plastic (for some people could be pro)
I just got these mags for my m4, and the color of it is slightly darker than the picture, but it was okay for my gun, the mags have no feeding issues, except you lose 3 bbs when you reload
I have these and a few hicaps and they do its job well. these are great because there cheap, reliable, and no winding! Exactly the same as the other color ones.
