I have a Gen 2, Gen3, Gen4. All in 308. Have never had problem one, what so ever. All are super accurate and reliable with factory loads and all kinds and country's of mil surp going back to 1978. When we have firearm quals at work and we all bring personal stuff to shoot afterwards, everyone who shoots any of my POF's fall in love with them. Having never had functional issues, I have not dealt with their CS for problems. I have dealt with them, asking about upgrading parts and about switching buffer tubes, springs, etc. They have always gotten back to me quickly, and were honest about things not needed even when they could have made money off of me otherwise. In my opinion most people on here that rag on them, and there used to be plenty, were people that bought POF parts(sometimes used) for builds and when their builds were shit, they blame POF, and then when POF's CS won't tell them what they want to hear, or ruins their day by giving them pesky facts, they blame POF. I'm nobody's fan boy, as I will no doubt be called after posting this. But then again, I have a DPMS 308 that has been flawless for over 10 years, and we all know from this site that DPMS builds nothing but crap.
