Killflash homemade

I have mainly PA LPVOs on my action rifles and I can't source killflashes for them.

So I made some from black pantyhose stretched over the ocular lens, held in place by the slip on lens covers.

You can't see it when looking through the scope although I'm sure it's cutting off some low % of light coming through the scope.

I've done the same on any lights attached to my action rifles.

It looks very ghetto until I trim off the excess pantyhose.

I'm going to take it out in the sun today to see if the reflection is reduced.

Any other ideas for homemade killflashes?

Would like to know how this turns out because I was just thinking of trying to source these for a rifle or two.

I took two scopes out in the sunshine today, a pantyhose treated PA 1x6 and a 3x9 without pantyhose.

The reflection was a lot less with the pantyhose stretched in front of the ocular. I was surprised on how effective it is.
 
'Ocular'? Perhaps referring to the objective lens, as the ocular lens is there the eye goes.

I've made killflashes for a couple of air rifles using thin plastic drinking straws stuffed into plastic tubing, such as an old vacuum cleaner tube, or PVC plumbing turned down to about 3mm thick on a lathe, the ID turned and polished to be a snug fit on the scope bell. With a bundle of straws pushed tightly into it, the front end levelled with a flat disc to a short distance behind the leading edge, I then use cyanoacrylate glue ('Krazy glue') to wick between them. Once cured, I can push the mess out of the tube, trim the back end level to the depth I like, re-insert and glue it in place. Then I used flat black Krylon to lightly spray from a bunch of angles, front and back, until all surfaces are black.

They restrict a bit more light than the better commercial ones, but they cost next to nothing and work well enough to prevent sun glare without a huge long sun shade tube. Might also prevent neighbours from seeing a glint from my scope when I'm nailing squirrels in the butternut tree.

Yes, the objective lens, not the ocular.

I did have the ocular caps open when I did the side by side test.
 
There is a guy 3D printing scope covers on g u n p o st, with them added if you want. For $55 each, that is a decent deal for the caps even compared to the tennabreax ones that are $70 plus each. And my son 3d prints, but these are a decent deal for the time and effort it would take to print some one offs for me.

I just ordered a set, but without the kill flash feature.

My understanding for a Killflash is its intended to reduce the glare off your optic giving away your position! Id be more worried about the flip up lens cover and keep the sun at your back. Just my idea.

One doesn't always have options when it comes to relative orientation with the sun. I found the 3" long sunshade which came with my Vortex 5-25x scope was somewhat useless when zoomed beyond about 18x. Glare started becoming a problem. But with the very thin paned killflash I put on to replace the long sunshade, this isn't a problem. The very matte black aluminum grid is irregular, no distinct pattern, and most of the shapes are pentagonal. Seems very effective at 'absorbing' glare.

Does it do anything for the ocular side of things? My understanding is killflashes normally function as a sunshade in addition to reducing glare/glint from the optic lens side?
