Wow!! Thats all that can be said after shooting one of these. A guy I never met let me and my son shoot his Barrett 82A1/M107 at the range today. Nice guy! Man, the shock wave one of these puts off is awesome, and after listening to 50 rounds go off, I was wanting more. I put 4 shots down range, and my 10yr old son, shot it once. The recoil was no worse than a 12GA shotgun, but the blast is something I won't soon forget! Heres a few pics of the gun, and me and the boy shooting.
