I got to shoot a Barrett 82A1 this weekend. (I think they cost more than my car...)
Yep... it was awesome fun.
(does my arm hurt? the spring takes most of the punch, but I have a right broken wrist ..old injury.. and I shot right, so it still hurts. My elbow slid several inches across the blanket. But ohhhh it was worth it.)
I don't think I've ever anticipated a shot more in my life. I couldn't tell you for sure, but I think it has a really long trigger pull. lol
