Before I pull the trigger on a FN Scar 17$$$.........

My needs: A well built 7.62 AR style weapon system that will run...Reliability is first and foremost of importance. Accuracy capability- punch center mass hits consistently on man size target out to 600 yards, If I do my part.
Nothing is guaranteed but want a durable rifle that can hold on over time, solid build quality.

The Barrett Rec10 has my attention. any users with input on this rifle, please by all means.
Also looking into the POF-USA Revolution, LMT MWS, Daniel Defense DD5.

POF and Barrett Rec 10 I can pick up now. Not seeing any online folks selling the LMT right now. The rifle I seek will not see a high volume of fire, maybe 150 rds a range session, 3-4 times a year. Ill be using 5.56 rifles for most of my training.
However of course I want a rifle that can take it if I need be.

Sticking to a "AR" style rifle would be nice, since I am most used to that platform. The Scar 17 is not far off, and I am leaning that direction. But I would like some solid accurate input from actual users to see what direction I could go.

Thank you.
