Question on ND filters and CPL on scopes

[Dlewis89]

I've been having issues with blowout (that's probably not the technical term, but the scope "washes out" in white shooting in high light or snowy environments). This is the scenario I'm trying to fix.

Granted I do not run ultra high end optics, however, I've heard people running diopters, cutting holes in scope covers and all sorts of things to cut the light coming into a scope. Probably cheap b*stards like me, but I got to thinking about.. Would a camera lense work on a heavy bench rifle and hold up? I ordered an Amazon CPL 55mm lense, supposedly very well built. I'm hoping to cut up or change how light enters the scope.

If it doesn't hold up... I'm out $11 and I learned my lesson. But if it crisps up the image I'd like to test and see if the lense
A: changes poi or changes zero through distortion
B: actually.. Holds up.

So along with this question will be an experiment. This experiment may take some time, as my job keeps me busy (military grease monkey) and they rarely let me out of the cage lol.

Just curious if anyone's done this before, tips, other tricks to stop large lense scopes from sucking in light (I've heard panty hose or flash hider works well enough, but I feel an adjustable lense will help fine tune light focus)

Thanks for reading, hopefully this isn't too stupid an idea. I'm not a professional shooter, just an idiot bumbling around in his own head lol

A 1/2” hole in the center of a scope cap works very well, doesn’t affect point of aim/point of impact, and you can flip it out of the way for low light conditions.

Do not use a CPL on the front objective, you will change your POA and it will vary by position of the CPL. Hensoldt used to make a CPL but it attached to the eyepiece, that’s the only position you will not mess with reticle shift. Better to get an ARD for what you’re experiencing. Tyler at MK Machining has a fairly cheap option.

I ended up doing just that.. My little $11 contraption idea didn't work, the threads were wrong and I anticipated that, but it was way too small to work with to retro redesign it...

This is what I came out with. I've been reading about pupil sizes and whatnot, the scope has a very large objective lense (55mm) that's probably my issue. I wish there was another way to kinda tune it and turn the light down though. I still havent gotten a chance to peer outside to make sure it's okay with all this snow. I'll be extremely happy if it cuts the light down. I thought a 5" shade hider would have done it but it was zero help...

Carry a roll of electrical tape with you to the range. Use that to reduce the size of the hole in the cap, if it proves to be too large.
