RMR type 1 may need repair?

[1KPerDay]

12K rounds riding on M&P CORE 9L, battery replaced once, had to shim it to prevent flickering. Common issue. However I am now having to adjust the R/L frequently. I think the 'clicks' are worn or zero mechanism has worked loose. I guess I send it back? Any ideas?

I'm starting to notice hearing loss; maybe I just can't hear clicks?

The clicks are barely there. Does the optic have any wiggle on the slide? Check the screws attaching the optic to the slide to see if they are snug or if they have loosened up a bit.

No wiggle I can discern. I've had it loosen a couple of times so I know what that feels like.

It can't hurt to back out the screws, clean the threads, use a drop of loctite 243 (blue) on the threads and torque the screws to 15 -18 inch lbs or "farmer tight". Let it cure for at least 12 hrs, ideally 24hrs. Zero the optic, and verify over the course of a few range trips that the zero has not shifted. Short of that not working I would just send it back and have trijicon figure it out.

They have blue loctite on them now but I may try again and mark the adjustment dial just to verify it isn't moving.

Try putting a wrench on the screws to back them out. If they come out easy you know it is likely a loose sight. If they are tight then save your ammo and send the RMR back to have them take a look at it.
