Blue Box 140rd Polymer Midcap Magazine for M4 / M16 Series Airsoft AEG Rifles (Color: Black / Single)

"I was a bit suspicious, at first, about these magazines. However, I decided to order one and I have been quite impressed so far. I have filled and emptied it around 5 times now and it has performed well. I'll go ahead and list my pros & cons.

Pros:
Strong polymer (not cheap plastic)
Light but not too lightweight (could be a con I suppose)
Holds 140 bbs (or at the least 130-ish)
Cheap (at least while on sale)
Looks good

Cons:
Last few bbs don't feed (not a hug con, happens in a lot of midcaps)

Double feed every now and then, but I think its cause they are new and the springs need to be wore down.

That's about it as far as cons. I might find a few more as I use them in game but overall these appear to be solid magazines.

I'd give them a 4.5/5

"One of the very few magazines that fits in my Matrix Calico Jack on top of feeding every round. Being only $10 is amazing, it's extremely tight in the magazine well. Though I had ordered 3 1 year ago, 1 had broke splitting in half. Not to big a deal since it is only plastic and $10 so it's expected. A newer more durable model would be amazing.

Alright guys, so I've had these mid caps for almost a little bit over a month now and they've been doing there job OK up to this point. When I first got this package I was very pleased with the all around design looking pretty cool for a good price. However, these mags are plastic, which leads to their downfall. My first indication was my brother telling me that some of the mags (We split them half and half) weren't feeding every time. This is pretty common with midcaps, so I just figured they weren't broke in yet. I told him to fill up his mags with the speed loader and then dump them out back into the speed loader in hopes that this common technique would "break them in". While in the process of doing this, apparently he managed to load them to much and the whole mag split in half. We then spent about thirty minutes finding the pieces and putting the mag back together only to figure out that the top was split to far so the mags wouldn't feed at all... In my personal experience with these mags, they seem to either not feed at all or double feed every 10 rounds or so (and that's on semi) So in conclusion, I would recommend going with the elite force mid caps (http://www.evike.com/products/39409/). They may not look quite as cool, but they are a better price, and they're metal which was the main problem with these breaking.


Pros.
Look cool
Lightweight

Cons.
Not Durable
Don't feed all the time
Can be overfed to easily

"I purchased these mags about a month ago and they don't seem to work in my Krytac Trident MK2. There seems to be no hopup, but when I put my highcap back in it works like a dream. I don't know if it's just for my gun but now I have to buy different mags so I would say I'm pretty dissatisfied with my purchase.
