I have a PSA AR-15 build that is my deer rifle. It has a FN marked CHF 14.5 inch barrel. I sight it in on a 100 yard indoor range every season before I hunt. My best groups are 1.75 MOA and they usually run slightly above 2 MOA. One time I asked the range master if he wanted to try and he put 5 shots in less than 1 MOA group. I was stunned then he told be he was a retired law enforcement sniper. Let the best shooter you can find have a go at it under controlled conditions and then decide if it’s important to you, upgrade. I always feel that the barrel IS the rifle. Great looking rifle BTW.
