I have the opportunity to buy a new in the box Barrett M82A1 .50 cal. The rifle comes with a new Swarvorski PV 6x24x50 scope. The price on this combo is $7500. I 'm pretty sure that this is a good price, just curious if anyone knows what this combo is worth? I dont plan on shooting this gun, but would buy it as an investment to sell at a later date. Whats it worth?
