Ar10 scope suggestions?

[bamban]

On one of my AR10s I have a Trijicon 2.5-10x56. Great short range hunting scope. I've taken it to 600 on steel, no problem

I get it. I guess I'm just accustomed to AR platforms for 50 to 300 work. I leave long shots to the bolt actions, but that is because I haven't set up an AR for long range. Sounds like a good project though.

I have some 223 ar15's 18, 20 and 24 inches SS piston rifles. They are fun and cheap to shoot at least in the past.

This is a light weight down to the titanium brake 20 inch 3 pound drop in trigger
