I rarely lap/ream rings because if you buy good rings and INSTALL them correctly they wont
mark your scope.

If they will not Aline properly I replace them If I can. If they are hard/impossible to find then
I will lap/ream them. But only enough to correct them. The biggest problem with reaming or
lapping is that to much material is removed and the rings will not hold the scope very well, so if you do ream or lap don't over do it.

I prefer Dual Dove Tail mounts and rings but you must get them aligned properly.(And don't
use the scope)For this I made a 1" and a 30mm mandrel that I use to turn the rings in and
align them.

Also on any dove tail ring I use anti seize to prevent galling.

The rail mounts are easier to install but after installing the rail on the action I use the mandrel
and tighten the rings on it before I tighten the ring to base screws. (this aligns the rings better).
And then re check the alignment of the rings.

There is no reason to mark a fine scope if everything is done properly including Reaming/lapping
if nessary.

    Re: Laping scope rings

    One other thing that I forgot to mention earlier, I've seen lots and LOTS of rings way over tightened and marking/damaging scopes that way as well. I use an inch lbs. torque wrench and set my base to action screws at 25 in./lbs and ring screws at 15 in./lbs and have had no issues on even the big guns.

    +1 there,,, except I go by the size of the screw for torque. I've had to take the barreled action w/scope mounted to the milling machine and mill the head off of a screw to relieve enough tension to get 'um out.

    Re: Lapping scope rings

    Burris Signature rings are the way to go: No lapping needed, no ring marks. Note: Nightforce instructions warn not to use turn in rings, for the reasons mentioned above: Using the scope to turn the dovetail can bend the tube.

    Lapping works but you only lap the bottom ring.

    Re: Laping scope rings

    I'd suspect the top half of a ring could do as much damage as a misalined bottom half. If too much is removed from the inside, take a bit off the flats where the screws go to get that 'clamping'effect. The only time I've used Burris Signature is when the mounting holes for the bases are not on the centerline. Lots of "home built" Mausers/Springfiels/1917s/1914s like that, as well as the occasional modern day factory rifle. If those mounting holes are off the centerline too far, even Burris can't help. Use something other than your scope to turn rings into their bases. Even a wooden dowel rod works pretty good.
