I have two 1 qt canteens (canteens are new, the caps are used), 2 used canteen covers, and a new pistol belt. (The belt and canteens were my former "inspection" gear, they didn't see any field time. The canteen covers and caps are well used, however.) The US CAV website lists the new prices at $35 for the lot. I'll let you have it for $25, shipped.
I also have a spare large rucksack, minus frame, if you need one. They retail for $70 brand new, minus frame. If you need it, make me an offer.
Send me a list of your AR parts you have to trade, I might need something.
