"Pretty good mags for the price. They have a little trouble feeding with full auto. Doesn’t bother me though because I only use semi automatic for the milsim a I do. Overall good for a starter gun.

"If you’re looking for magazines that fit and feed without having to rock them back and forth to lock in for the Cybergun m4 series then these are the magazines for you. These magazines fed flawlessly for me and I bought 4 of them because they were super cheap so BUY THESE MAGS. Tldr:cheap, reliable, well feeding magazines just buy them.

"Review for "6mmProShop 140rd Midcap Magazine for M4 M16 Series Airsoft AEG Rifles (Color: Grey / Single Magazine)"

Price paid at time of review: 7.50 per mag

These things are AWESOME. However, the bag the magazine comes in says 130rd, while the advertised title is 140. The mags do hold at least 130 bbs (I used a scale and measured the weight of BBS) which I find is more than plenty before a reload. This might also be the only brand of magazine that is accurate and holds the advertised amount. There is a small follower as well which prevents some BB waste when a mag is taken out. They're extremely lightweight, and no metal means no rust over time other than the spring which can be replaced. All in all, the best midcaps on the market due to price and reliability. If a mag doesn't fit flush in your magwell, you can use velcro tape on one side of the actual magazine to make a more snug fit.
