Going to bump this thread even though 6 years old. (sorry!)
A buddy of mine lent me his brand new comp m2 with mount last weekend for some shooting, I put about 400 rounds through my AR on it and it was amazing. I offered to buy it off him, but he's a little reserved.
What would be a fair price to offer him? Most i see online go from anywhere 250 (used) up to 450 (new)
Any input is welcome.
