I have one carbine that I really wan’t to make an Acog/DI RMR combo work effectively in low light.
Has anyone on here ever experimented with attaching a small led on the fiber optics of an RMR?
I was looking at this….

Opinions?
It’s a neat idea, although I think you will have a challenge to work out a lighting system that parallels the ACOG’s reliability. Or even sufficient reliability to rely on for that matter.
What light are you using on the gun? I’ve never tried it with a long gun, but my TLR usually illuminates my RMR fiber adequately (but not optimally) via spill/reflection.
Plhv2 on a m600df body.
I was just thinking of installing a light similar to the link I posted on the rmr. The Acog, I’m not really worried about, because the reticle is etched.
The light in the link, could be installed in a small section on the rmr’s fiber optics, and covered with black tape. I could sleeve the wiring, and switch…and figure out where, and how to mount the battery holder. The light would only need to be used in the conditions that plague DI RMR’s.
What do you think?
Hmm, I’d have expected that to do well, but I guess the dot washes in the hotspot reflection?
Unfortunately, yes.
I’m intrigued by the idea, honestly. If I had a 'Cog, I’d probably try it and see. You may end up hating it, and you may end up loving it, but you won’t know until you try. Is the brightness on that LED adjustable? I can see it making the reticle bloom in the dark if the LED is too bright, but I’m just guessing.
I’m pretty sure it’s one brightness. Now I’m wondering if I should look for a dimmer one.
I think I could dim it various ways. I could add a resistor, I could paint the led with enamel, or I could possibly dim it with a strategically cut heat shrink tube. There are work arounds, I just need to experiment a little.
I just wanted to update this thread.
I got my micro led last Friday, and did some experiments. I have been super busy, but things look very promising.
The light seems to be absolutely perfect for this use. It illuminates the reticle on my cog about as effectively as in the house, with the lights on.
It doesn’t bloom the reticle even a little. I darkened my room, with the door open, all lights on outside my room…simulating the situation in question.
I also ordered, and received, a Vortex spare cr2032 picatinny holder, and plan to convert it into the base of the unit. It looks pretty straight forward, possibly easy even.
I will post a picture of the finished unit if I ever get time, to actually finish it.
Well, it works well for the cog, but the cog don’t need it. The rmr has terrible light gathering properties compared to the cog. The led is nowhere near bright enough to make any difference, when aiming into a bright area from a shaded area. If I go any brighter, it would be visible by others. Luckily, I only put a few hours, and $20 into this ordeal, as it’s just a lost cause.
Time to get something else, I think.
