I have a gen1 PSA PA-10 and love it. It hits the 550 yard gong at my local range without issue using 147 gr NATO ammo. Im sure it would do farther but that's the max distance at my range. I did put a geisselle SSA-E tigger in it but for under $600 shipped you can't beat that with a stick.I'm having a difficult time actually going through with the PSA .308 ar15. I can't seem to find good reviews, but then again most of the negative ones come from people who didn't realize the uppers and lowers were proprietary and tried to build them with mix matched bubblegum. I tend to spend a loooooong time reading up on stuff before laying my money down and the time restraint of this sale rushed that just a tiny bit, haha.
As for AK vs. AR in a SHTF scenario, I would go AK. The rifle has been proven over the last 6+ decades to just work. In a SHTF scenario, you're not worried about 600 yards or tacticool features or this and that. You need something that works every time. I have a WASR with 1000's of rounds through it and wouldn't hesitate to grab it. In fact I would take it over almost every other rifle in the safe, and it's configured as it rolled out of the factory. Actually that's not quite true, it has a slide fire on it at the moment....
(Another bump for PSA inbound)....PSA has their AK's for $500 shipped right now. I would love to get one of those as well as another PA-10 but one only has so much money and I have a harley to pay off.....
