I am using some cheap scope from Marstar, a 1.5x - 6x, but works just fine on my norc,
which also works just fine. They also have a 1.25x -4x w/bullet drop settings. Both are around $135
probably will upgrade scope some day when I also upgrade AR to better model.
Dont like 1x scopes as like to have better view at longer shots. not too many options out there
for 3gun style & at decent prices.
