I am going to be purchasing one of the new Nikon M-223 scopes and want to put it into a Larue QR mount. I checked on Larue's site for mounting instructions and they were kind of vague. Can anybody give me some pointers on how to install a scope in the Larue mount system? I have never mounted a scope in or on anything so I have no idea as to what tools I will need and how to do it.

Thanks,

The LaRue mount comes with the necessary tools to mount the scope into it. The LaRue mount has 4 screws on each ring. The way I prefer to tighten these is similar to the way you tighten lugnuts. I tighten say the top left, then I got to the bottom right, then top right, then top left. Then I go back over it once to make sure everything is still tight.

It says in the instructions that come with it to tighten the bottom two first then the top two.

So you don't need to use a bubble level to level the crosshairs?

I went thru this with my Aimpoint figured its the same as a scope. Here is a link

I've never used those things and I've probably mounted 2-300 scopes. We do it where I work. I've never had anyone complain about it not being level.

Oh,
well hell thats what I did then if its what the instructions said. Its
been a while since I mounted my scope in the mount.


But thats how I do my regular scope rings though. Tighten diagonally.

I do it this way as well. Once I have it tightened down and I'm happy with the position of the scope and crosshairs, I remove one screw at a time to add a dab of loctite then tighten them back down. Sure you can just add the loctite the first time around but I like doing it my way just in case something is messed up etc.

Lower bolts first, then top. after I get everything tight then I torque to 15 inch pounds lower then top. Definitely use a level or a plumb line. I started using the feeler guage method a couple of weeks ago and it definitely helps.

Any link describing the "feeler gauge method'?

I think I saw it in the precision rifle section of the armory. but basically you use feeler guages between the scope and base to help level the scope. I think it helpls to keep it from moving during the torquing process.
