I like the Colt 6920 and the Rock River for the money.
I have a 3x9 Vortex on the Colt and i have an Eotech
512 on the RR.
The Eotech is nice No magnification 1 Mil red dot
and i can regularily hit Skoal cans at 110 yards with it.
I put the 3x9 on the Colt 6920 as it has the 1-7 twist
bbl and i can shoot heavy bullets at longer ranges.
Colt 6920 around 1000-1100
Rock River around 1100-1200

Vortex scope 3x9 120-150. You could get Nikon 3x9 BDC for a little more 170-180 Both are good glass.
Eotech 512 400-450

Then a couple of aftermarket triggers and you are
good to go.
