I came across an 18” fluted 6.5 Creedmoor AR10 barrel and now I need an AR10 education.

From my reading there are not the standards that exist in the AR15 world.

My goal is a lighter weight rifle without going nuts spending money chasing all the ounces. 7-8 pounds without scope is the goal versus the ~13 pound guns out there.

Can you point me in a direction for the basics or line them out for me here?
