MAG 2500rd M249 Electric Winding Cartridge Pouch w/ Remote (Color: Desert)

"I've been using MAG Brand 'Nutsack' box mags for M249/MK46 for years. Never had any problems with any that I've owned. I currently have one that I bought about a year ago, and it's also working fine. Feeds an A&K branded 'middleweight' MK46 using the remote switch, and it feeds well and keeps up with a modified high ROF build. Not sure what happened to the other reviewers, but I felt it was worth a better review based on my experiences.

"I bought this about 4 months ago and used it 4 times. In that i have had nothing but issues and problems. the first is that if your using an A&k this will not fit in correctly and will require slight modification. Next is the way that you have to feed the BBs into the mag, there is a small port that is no bigger than a dime. This is absurd because we support gunners have to carry 1000 rounds in that little box mag which is a pain. After the first use of the box mag the pressure switch actually broke off of the wire. The way the wires where connected looks like what happens when you teach a 10 year old how to soder wiring. Overall the last one could just be me but the other two are for everyone ( i have multiple 249's), but when the box mag did work it was quiet, efficient, and most of all it kept up with my 33 RPS.

"I bought this for my a&k m249 and the first day I had it (no play time with it) it stopped working. We took it apart and tried to fix it but it still isn't working, because of this I had to buy another one because I was going to a milsim event and there was no more time. The second one lasted through the event although it ran very
rough it would stop working and would I hit it and it just started working again. As soon as I got home it quit working, now I have two to fix. Overall it is definently better
then the junky a&k box mag when it is working. Also if you have a and a&k m249 it will take modification to fit right.
