1-4 will work out to 200 yards with ease, had a Nightforce 1-4 and made 300 yard shots with no problem.
In the 1-6 range, Kahles with 3GR is hard to beat. Amazing FOV and clarity, reticle is very easy to use.
Scope is also lightweight on top of Carbine. Recommend that you try to actually look through your top choices side by side.
