"I started playing airsoft 6 years ago, and these magazines are my number one recommendation for any sort of M4 platform. I’ve got 16 of these magazines at the moment but used to have 20. I always buy the bulk pack because they’re just so cheap, and perform amazing. After constant use and abuse, only 2 of the 16 have any sort of issue, which is the glue holding the two halves together is starting to come undone at the front. A quick super glue and electrical tape wrap solves the problem no issue

"have owned 7 of these mags for a year so far, have used them at milsim and field events. They have been rained on, stepped on, dove on, bashed around, thrown, and dropped. yet they still work like the day they were received. definitely buying more to fill my teams need for another milsim event!

"These mags are light and feel kind of cheap, which they are, but they work great. I have used them for several weeks of airsoft and they have held up great. They are light weight and I am not turning wheels anymore.
