Avengers Polymer Magazine for M4/M16 Series Airsoft AEG Rifles (Color: Translucent Green / 370rd High-Cap)

"Alright, I got 3, 2 of which are now broken the same way, the clear plastic on the top is only secured at the back of the mag. The plastic snapped and broke the mag, while one is unfixable, the other can be repaired by glueing it. Other than that, great mags! I would just suggest glueing the tops, near the front of the mag just to be sure. I used these with a EMG Umbrella Corp M4 for reference. I've dropped these, thrown them at brick walls HARD, they are great. feed well too. good mags that will last.

"Mags are very durable and feed flawlessly. I've dropped these and throw these and they have still feed perfectly.
The only reason I rate this 4 stars is because they wont feed .32g bbs. The spring isn't strong enough but I guess that's why they're cheap. If you don't plan on using .32g bbs then these are amazing mags, otherwise don't bother.

"good and bad. in my experience, it is quite good

pros:
- looks sick inside my cybergun colt sportsline M4 Block 3.
- sturdy, wont break easy, and a translucent top makes over-loading not possible.

cons:
- doesnt feed too well in my sportsline Block 3, will fire around 10 BBs then wont fire 1 bb, then alternates between firing, and not firing a BB.

"Overall impression: not bad. Not on a par with the original (and no longer available sadly) PMAGS, but overall good. They're about 1/2" longer than standard PMAGS for some reason, so keep that in mind for pouch size, etc. Also a bit loose in the magwell of my M4's and VFC SCAR, but they feed decently to within a couple rounds...As a PMAG alternative, they're acceptable.

"I bought two of these magazines and one of them was able to be spilt and detach the internals from externals. Also, they only loaded 50% of the time. Buy a different magazine.

"These are good mags, I’ve played a few games with them. They feed very well. I ordered 5 of these mags and one of them broke on my first game with them, the pull cord snapped off. Secondly, the little sliding door on the bottom of the mag tends to fall off pretty easily, I’ve resorted to just taking the entire thing off when pulling the chord.

"I got the black Flash Mag variant, and it isn't great. The winding cord is metal and the rest is plastic. It came manufactured to not feed. The BBs can't be pushed up through the end of the magazine because they push the plastic on the inside apart whenever you wind it up, and it releases most of the tension.
I want to like this magazine, it looks and feels good overall. However there are definitely some functionality problems. I'm giving it 3 stars because all though my magazine did not function at all, I haven't used the high or mid cap, and the outside quality is pretty good.

FLASH MAG REVIEW:
Good:
* Exterior quality is pretty good
* It fits pretty tightly, so the high-cap and mid-cap are good fits.

Mediocre:
* The clear plastic is somewhat fogged, making it hard to see into the BB well
* Sharp corner on the bottom of the mag makes taking the cap for the winding cord off painful if you aren't careful where you position your hand
* The cap for the bottom of the mag slides off, so you might lose it if you set it down or put it in a loose pocket
* Plastic flakes (?) fall out of the winding cord when you wind it at first, which made me think I was grinding up something, which appears to have been the plastic holder for the cord.

Bad:
* It wouldn't feed past the first few rounds out of the box. I took the mechanism out of the shell, and what looks like would happen is that the pressure of the BBs in the feeding tube would be too much, and the middle of that, where there is nothing holding the two halves of the internals together, would split apart and refuse to pressurize any further. The first round or 3 would release fully pressurized, and the rest wouldn't have enough energy to get out of the magazine.
* The winding cord catches pretty frequently 1/4 of its length of the way out on the return trip, requiring you to hit it or be either gentler or more forceful, typically more forceful, on the cord going back in. It seems like there's a gear on the inside that's getting caught against the inside of the shell
* My BB catch nub came cracked and with a chunk missing out of the end, not sure if it's gonna hold up to high pressures
