Glass suggestions on a budget

[VASCAR2]

I have the Leupold Mark AR 3 X 9 X 40 mil dot and the instruction state this scope can be used with either 5.56, 7.62 or other calibers. The instructions explain how to use the mil dot and how to sight in for your caliber. I like the mil dot plus the ability to dial in the range if I have time. I think this is a good scope for the money plus I like the size on my flat top 16" carbine. I'm using a RRA cantilever mount with thumb screws. The only thing I was surprised is the 40 MM objective does not gather the light as much as my 2.5 X 10 scope with 50 MM objective even though this is a cheap Famous Maker scope.

I decided if I was going to be hunting in low light/night I might switch optics and put on my Vortex Strike Fire red dot so I keep the red dot which I sited in for my 6.5 Grendel in my gun case.
