"Great midcap. Fed my custom combat machine and evike custom m4 perfectly at full auto. They need to be broken in a little to be able to fit a full 140. Canít go wrong for the price.

"JUNK! Nothing but feeding problems with 4 guns, (EF tar, G&G m4, Colt m4, Hershel Scar L), I had to put tape on the back of all mags so they fed right. They do make great grenades tho as they split open very easy, so load them up and throw at wall during your next CQB!

"Now I am sure these work for some people but not for me. For the first few hours, these mags worked flawlessly. I was Happy that they were able to work right out of the box. But as the day came to a close they started to die. One of my 3 mags was absolutely in ruin and was unable to be loaded at all. The other 2 were also not loading correctly into my Classic Army KM10. Now, these mags may work for you but just note that they are not the highest of quality. For the price, they are decent mags but if you are planning on using a mid-cap for a long time these may not be the best mags for you. But if you are just getting into airsoft and you don't want to go over your budget these mags are a cheap option.
