"The other guy said they these mags aren't snug enough, but in my case they were too snug. They seem to have a weird size...
I had to sand down the sides a bit in order to get it in my M4.
Other than that, great midcap no problems!

Stuff to know:
- Grey colored
- Hard to load without a speed loader

- Cheap
- Sturdy (Great plastic!)
- Good weight
- Nice and silent (like most mid caps)

- Only 140 rounds
- Weird size

Overall, I would recommend!

"These magazines are great for the price, but one error by Evike kind of ruined their external for me.

First off, I found these mags do feed quite well, especially in high speed setups (Ran them in a 25~30 RPS SSG set up). However, I find that four of the six magazines jam quite often if loaded up with more than ~60 rounds. Thankfully, I mainly use these in my DMR set up rather than my high speed, and only load about 40 rounds into them and they work without a problem.

Now to the mess up, I do not know if it is standard for Evike to put the bar code sticker onto the magazine itself, but when I received my six magazines, each one had a large bar code sticker near the bottom of the magazine. If you have never dealt with those stickers, they are a major pain, and after scraping each off, one at a time, I was left with this stick residue. After an hour of scraping with alcohol and rag, I gave up and spray painted each magazine in matte black, which turned out to be better than the standard color anyways.

Overall, if you are on a budget and looking to buy a few midcaps you cannot go wrong with these and hopefully you have better luck with the packaging than I had.

"These mags are actually really great! They don't feel that "plastic-y" like a lot of other cheap mags. Although very lightweight, these mags feel very sturdy—so if you drop them, the only bad thing would probably be a scratch or dent, of course, worse case scenario would be a crack. The mag that I received has a somewhat "seamless" design so you can probably beat on these pretty good without having major or some minor problems.

They feed really great even at the start of the "Break-In" period, and I'm still in the process of breaking-in the spring in the last mag.

-Precise Feeding (MID-CAP POWER)
-Sturdy design

Cons (Nothing Really but...):
-A little wobbly to the touch for my A&K Stubby Killer M4, but nothing really bad even when the gun is moving around a lot. It's compatible, just not "snug" enough to fit the magwell.

I love these mags overall. They will last as long as they are properly cared for! (Lubing, Cleaning, and Break-In)
