Not a scope expert, but one of the things I always look for is a light transmission percent.
Not many scope makers list that number in their scope specs. or description. Being me, I just assume their number isn't very good and they leave it off to keep from being compared to manufacturers who have good light transmission percent performance from their scopes.
It's one of those things that I look for when getting ready to buy a scope.
At one time I thought a bigger objective lens would let in more light and make the scope better in low light conditions. After buying a Simmons 2.5X10 scope with a 50 mm objective lens I was greatly disappointed at how poorly it performed under low light conditions vs. several 40 mm objective lens scopes. Sometimes, even two scopes from the same maker with the same power range and objective lens size do not perform the same under low light conditions.
Like I said, I'm not a scope expert, but there's a lot of things that go into making really good rifle scopes that the makers don't go into with their product descriptions.
Either they don't think it's important, or they've got something to hide that they believe would negatively affect their sales.
