Gk tactical 400 rds drum mag 

I have skirmished a few times and is great fun, is gas tight and cycles fine, on occasion the rounds may get stuck and you need to press down on the rounds with something thin for the rounds to spring up to the top but this has only happend a few times and the same thing happens on occasion with one of my mws mags.

Other than that is a nice piece of kit and I'm selling as I don't really field it any more.

Price includes delivery and pay pal, can sell a bit cheaper if collected.
