Bolt Airsoft BMAG 140 Round Polymer M4/M16 Airsoft AEG Magazine
(Color: Tan)

"I got three of these, and they all fed well right out of the box with my E&C AEG. They look great and fit with little wobble. It loaded 120 BBs straight away without much resistance, and I'm sure it can hold more, but I can't bother to test again and count. For all three of the magazines I got, the follower sits about 1 BB's length below the BB release nub, so when you empty a magazine, the usual 2-4 BBs fall out of the hop-up unit, and 1 more sits in the magazine. Not a big deal though. Depending on your airsoft gun, these magazines may (at least initially) have some issues with dropping free from the magwell. You could determine what's getting stuck and sand it, but I didn't go that route. I just reloaded until whatever part of the magazine was causing this got ground down.

Positives:
* These look great and are built well
* They are very grippy on the bottom half to facilitate easy reloads
* BBs load into them easily without modification or breaking in
* They feed very well immediately

Annoyances:
* The follower is a bit short, so 1 more BB goes unused and sits in the magazine
* I had slight issues with dropping free initially

"---A REAL REVIEW, NOT A "JUST GOT THIS TODAY" REVIEW---

The BMAG is what you expect from a $10 midcap. Its plastic, lighter than my other polymer magazines, but needless to say feeds all the round through up to about the last 2 or 3. Great for anyone looking to get some Magpul PMAG esque magazines without paying a $15-$20 per mag.

Pros-
Works, has worked, still works.
Design closely replicates Magpul PMAG (no window)

Cons-
Depending on your taste of tan or the color of your weapon, It may not match.

"Good mags, pretty reliable feeding. Good build quality, but not really meant for rps builds from what I’ve seen. Does not drop free from the mag well. I have a few of these but will not be buying anymore because of the mag leaving 1-2 bbs
