Wish I owned one.
I have driven them many times.
Took the SCAR 17 (.308 WIN) out today to check the scope @ 100 yards.
My first round jammed and look what happened. The next 59 rounds cycled just fine. I was using the Winchester 147gr FMJ White Box ammo and I've read it has had some problems. The Range Officer freaked out kinda. He said he's never seen not only the round bottleneck flatten out but also lip over on the side. Not sure you can tell from the pic but it's really Fluked up.
I wonder if there was an obstruction of some kind or the bolt carrier jammed it inside the receiver? Either way it worked like a charm after. Every shot hit the paper including the foul.
