Sadly there is a POS from Indiana. Yet these motherfukers have no problems increasing their benefit package. On the backs of those who actually deserve them.
I am a fan of Rock River LAR8 and Aero Precision M5 have them both. That being said Armalite has good value for the product. I have shot the LaRue and it is a damn nice rifle. I like LaRue's other product's as well. I have their grips and trigger.
Welcome from Indiana brother. Where some people got into having problems with PA10 was trying to mix and match parts. I you stay with the same upper and lower it should reduce the likely hood of issues.
