They can help protect the objective but I think flip up lens caps protect better. You can use both.What's the skinny on scope shades -do they diminish a scopes ability to gather light ? I like them because they seem help protect the objective lens .
I'm going to presume you're asking specifically about the extensions that screw on the objective and extend forward several inches. As long as they're black matt internal finish and don't reflect light (they're designed not to) then they do not diminish light entry to the scope and to your eye. And they can actually improve vision by reducing light reflection and scatter off the objective lens. On the negative side, they can be a bit bulky and interfere with the ease of packability of a carry rifle. I have a Kifiru gun bearer sling and with the sunshade installed on my scope, the interference with the Kifiru required me to remove my sunshade.What's the skinny on scope shades -do they diminish a scopes ability to gather light ?

Nightforce has great tracking capabilities, they are rugged, a bunch of elevation, holds zero forever, and reticles are designed for long range shooting. So if you are looking to shoot long distances constantly, then you need a scope that can take the abuse. -- gilmillan1
Nightforce is such a solid combo of reticle, available elevation, glass that is good enough to shoot at the longest range you can dial. Nightforce has bullet proof construction that can handle the incidental horse rolling or some other rodeo action. -- bigngreen
The total package. Nightforce is the best I have used as far as turret feel and solid detents. I have never had one that didn't track right on and always return to zero. Nightforce NXS is the best value for everything I need. -- Broz
