Sig Romeo5 Issue

[JB2000]

FYI in case any of you run into a similar issue.

I was shooting my AR9 last night and the Sig Romeo5 on it turned off and wouldn’t come back on. I assumed a dead battery, replaced it, confirmed the dot was on and raised it to fire. Dead dot. I tried reinstalling batteries a few times and got the same thing; the dot was on after I reinstalled the battery, but dead when I made ready to fire.

After I got home I started looking over the sight, cleaned the contacts, etc. and noticed the brass colored ring the battery sits in had backed out a little and was not making good contact. I’ve tightened it down again and the sight seems to be working fine. I’ll keep an eye on it a check it periodically in the future.

It backed out under normal use? Or when you swapped batreeze?

I have had good luck in the past with my R5 optics. But there handgun optics I had mucho similar problems with a couple and won't run them if they start acting up. Good luck on your rig to fix it.

My impression is that it backed out under use. It doesn’t appear there is any loctite or anything keeping it in place, just friction. I was thinking of adding a small amount of loctite but need to be careful as it’s part of the electrical connection.

I have as well. This is good information on something to watch for on them.

Sounds easy enough to fix.
