Thanks everyone who replied. It's helped a bit to a better understanding of it and the price factor.
I will probably take a walk on it tho, unless I can get it for around $2-250. I just think he overpaid for it when he got it, and trying to make a few extra bucks off it or trying to re-coup a bit from me? He sold me an as new unfired cva optima V2 .50cal pistol with a Leupold var-x 2.5 x 8x EER scope mounted for $300. Retail for the pistol alone is $400 (camo furniture), and the scope is perfect, so I'd think between 300-$400 on it.
He also has that Thompson Center .50 cal Scout Carbine he's wanting to sell me. Today he gave me a definite price of $300 for it.
It's nice, but not too sure on it's price either.
