Unless you just want that hand guard etc... the DPMS Oracle .308 can be had for the same price or less right now. And DPMS has been doing the .308 AR platform right for a loooooong time! PSA has been selling their .308 stuff for only a little while!
7C$'s is a great price for most any 308 sized AR. But I seem to recall some chatter about problems with the PA10 some time ago.
As stated above,for the same price I would go with a DPMS any day of the week. I have one. Bought it about 2 years ago. Cost me a thousand bucks. Great gun but when you start at 1K you can get really expensive really quick. I know I did.
When you start at $700 you can budget for a bunch of add ons. And . . . believe me . . . no matter what gun you choose . . . you WILL add on. --- SAWMAN
