I took my all brand new DMR this morning.

Larue LT104 and a Leupold optic..

I was very excited. Seeing all the tight groups while zeroing was a joy... until after about 20th shot, I noticed the scope canted in the ring.

Maybe I didn't tighten enough so I re tightened with the star shaped wrench that came with the mount. I was able to tighten.

Nonetheless, the scope still canted in the same direction after a few succeeding rounds. I got mad and came home. Realigned the reticle then tightened more.

My eye balls are literally hurting from aligning the reticle and I would crap my pants if I had to realign the reticle again. At this point, I might as well just weld the scope to the mount, joke.

Is there any agent I can apply around the ring to prevent the scope from rotating/canting without unscrewing?


Thanks,

1) Are the rings the right size for the scope tube (I assume so)?

2) Did you use an appropriate torque wrench/driver to torque the ring screws to the appropriate amount recommended by the manufacturer of the rings?

3) Did you use a thread locker (loctite blue) on the ring screws?

1 inch yes

I did when I first got it but then I remember the gun falling off from the table shifting the scope backward. Maybe that did something. After that I kept tightening it more and more until today when I took it out to the range and realized that the scope is loose.

3) Did you use a thread locker (loctite blue) on the ring screws?
Larue tactical sends screws with red loctite on the thread

I think you might be onto something here... I would be tempted to take the scope out of the rings and take a caliper to the scope tube... check the diameter in several places along the length of the tube - and at each place, spin the scope to see if it is "out of round" - if it is, the caliper measurement will vary as you spin (rotate) the scope.

Just checked and the variance is within 100th of an inch

I've coated rings with a thin layer of rubber cement before. It eliminates ring marks. Never had an issue with it.

Make sure you are using a arisaka type tool if you can. It makes the process alot easier.

Thanks for the suggestions.

It turns out I made a retarded mistake. I put the screws in the wrong hole.

Both Leupold and Larue said painter's tape or any sort of insert is unnecessary.

Thanks people.

Glad you got it sorted out and let us know!

Took out to the range.

It doesn't seem to be canting anymore.

Thanks!
