WTS: M7 10 round linker/delinker (.50 BMG)

I have one for sale $85 + S&H, I don't know if it will fit into one of those new flat rate boxes that the PO just came out with. I'll go by the PO tomorrow and see if I can get one, if it fits I'll ship it that way. If not, I could always see if it will fit with the handle off in one of the smaller boxes.
