Dimming a Red Dot Finder

Is your red-fot finder or red multi-reticle finder still too bright on the dimmest setting? My multi-reticle finder has 7 brightness settings, but the dimmest setting (1) was still too bright. Now, the simplest of mods has made all the difference.

I had some ND0.6 gel film left over from making a neutral density shield for my laptop. Using two thin, small strips of double sided sticky tape, I stuck a small piece of gel film over the reticle "port".

I noticed no deformation, shift or lack of clarity in the reticle. The reduced brightness is equivalent to 3 steps - that is, the brightness of Setting 1 without the filter is equivalent to Setting 4 with (which is logical, since the film has 25% transmittance). I now have a much more usable range of brightness settings.

Of course, you'll need some suitable neutral density (or perhaps red) film to do the mod.
