Quoted:Only problem is it completely blocks the dot on my RMR so I can't use it with my pistol.

Depending on your filter, the redder wavelengths of visible light will still get through. They're just attenuated *a lot*. This works well for me, since for my equipment the level at which the dot is visible through the filter is also the level at which you can use the dot with a white light through your non-NV eye. (this might lead to some glow from your optic visible to anyone else using NV without a filter)
I have found this to be the case with several types of Aimpoints, plus my pistol dot - all are red. I have some camp lights that can shift through the whole rainbow. Red and orange are can be seen with the filter, everything else gets blocked.
Another cool thing about the these is that the same thing that renders LED lights near-useless for IR illumination with flashlight filters lets you use white LED light + a filter on the objective without blowing out your NV image.
It may vary by filter, but 250-300 lumen white weapon lights are a little less bright under the filtered NV than actual IR illuminators. This means you can use a weapon light with irons/day optic on one eye without taking the NV off the other. Not ideal, but it works fine.
Incandescent lights and Sodium street lights will be attenuated a bit, but will appear much brighter than anything LED based. This is because the spectrum they put out is a bit messy. The filters also cut out most visible sky-glow from nearby cities and towns; on cloudy nights, instead of dark trees and structures against a light sky, you'll usually see them as bright against a darker sky.

I tried these out after seeing SkyPup mention it on an older thread. I use one on all my stuff now, as do my friends.
