I shot a Barrett .50 Caliber at an invitational machine gun shoot a couple times, and it was event I will never forget. To ring in the big 30 (my birthday) there is a high chance I would like to gift myself this mighty beast. After doing some basic research, I think the M82 would be a better option than the M107. What Ive heard is that the differences are fairly minor and that the M82 is significantly cheaper. Say I can get a decent deal on one, on the low end what should I expect to spend with the item and a nice scope? Is 6 or 7 total possible, or am I being unrealistic? What is the industry rate? I.e. when a dealer buys the gun for his or her shop, what does that person have in it, and how much markup? Usually Im pretty skilled at finding a deal when I am patient. Thanks!
