Brand new in box CA M249 BOX MAG OD.
I got this when I purchased my CA M249 MKII. I already own a Para model, and I have tan MAG version as well no need for three Box mags. I only tested it once to see if it works. These things go for $100+
I will toss in brand new 9v Duracell with it.
I will sell it out the door $85 no low balling
