Well not much comparison I guess really but I'm curious as to others thoughts on PSA. It would be used mostly inside 150yds on small critters and steel. I had a SS 1:8 WYLDE PSA but I only shot it open sights so I can't really vouch on accuracy. This is what I'm looking at now. It comes with nickel boron BCG. http://palmettostatearmory.com/psa-...upper-with-nickel-boron-bcg-ch-516446047.html I have a stock of 55gr hornady soft point bullets so 1:7 twist also has me apprehensive. I don't evet do mag dumps and would be happy with MOA accuracy. That's a good deal if it is of any quality. I have also been liking at White Oak SPR uppers. That run $685. Yes I do belive in you get what you pay for most of the time. Thanks. PS: admin maybe this should be put in ARs for varmints sticky.
