I'm pretty happy with mine. It's an incremental improvement over the BT10 line, which I had one previously. The biggest difference is the non-rotating lower legs and the deeper cuts on the tension knob for improved grip. If you need a new bipod and aren't sure if you want to wait for a PSR, there's nothing wrong with the BT10 as is, just get the QD mount if you're planning on putting it on a Picatinny rail. Makes it a breeze to switch it between guns. I switch mine my Savage 10 and my CZ 455, because why the hell not?
I doubt it's going to be on any list, there's already a couple in Canada. Atlas offered forum members at Snipers Hide the chance to pre-order and get the first PSR off the production line. I got mine early this year. Hopefully they become available to you soon, they're pretty nice.
