Looks like when I got my gun it came with a American Tactical AD Ops AR15 magazine. Looks very heavy duty and is heavy! but from the reviews they are junk. I have 7 Colt M16 magazines, 3 Gen 2 P mags and have 2 Emags on the way. Should I spend the $29 on a FDE painted FN mag? I kind of want one to keep it orig BUT $29 for a mag is pretty up there in price. But if they are pretty good I just might buy one to keep with the gun.
