This mag is 2 of 2 I am selling, there is a second auction for number 1. It has barely been used, I am sick to death of issues with my 249 so it’s going in the parts box and I am moving on with my life.

I have dusted it up with some Krylon paint so it didn’t look fresh out the box when I first used it. Importantly please see the photos, I have cut the ridge off the bottom of the feed block, this is so you can put it into the replica without having to remove the box from it. You can plug and unplug the feedblock of the mag with the box still attached to the replica. This is an age old mod I have done yo every M249 box mag over the last 20 years.

Please also see the photos of the box mag catch. Now this wouldn’t fit my A&K M249, the plastic on the mounting catch was too wide to fully lock in. As such I have had to grind away a bit of plastic. It fits very nicely now in my A&K and my mates Novritsch but I cannot guarantee fitment on your replica regardless of brand.
