Colloquially known as the "nutsack", the M249 saw belt carrying bag.

NSN: 1005-01-334-1507

All of these are in Woodland camo and are still in the original packaging. May have wear from storage or slight tears to the outer bag. We also have a few that are used and out of the package. 

These will fit belts of the 100 round nature. 

No Cherry Picking, Sorry
