What should the proper torque specs be for mounting a Vortex Razor 1-6 Gen II into a larue lt-204? I've heard mixed things.

Thank you!

I believe Vortex recommends 18 inch pounds.

That is exactly how I did mine.

Thank you for the reply. I called this morning to Vortex, but the gentleman didn't seem too confident in his answer of 20 top then 25 bottom.... Glad you clarified. Thank you!

Why no loctite?

We've tested this and seen it go as high as 25 inch pounds, which is significantly over our recommended values and more than enough to cause problems in tracking, maintaining zero, etc.

Hope this helps!

Thanks for the explanation! Would you have any worry of screws backing out without using Loc-Tite?

If you find the coefficient of friction for the thread locker you want you could calculate a torque spec.

Definitely not, I've never had any optic mount bolts come loose, or any torqued bolts for that matter.
