Scope ring Lapping?

[quadrafire]

Anybody do it? Do you see any great benefit, that would make it worth the effort?

Gunsmith - Lapping riflescope rings to improve holding power

[fair-chase]

Never even considered lapping my scope rings. Thanks for bringing it up.

I think I will check mine with some plastiguage before making a decision on wether or not to lap them. If they are as bad as the ones in the video I would definitely do it. Those didn't offer much holding power looking at the contact areas. Thanks again for the info Quadrafire.

good info. ill be checking mine. doesnt make sence to mount a high dollar scope into rings that arent true. thanks

If you use Burris Signature rings, there is no need for lapping:

You see this with a lot of guns that mount the scope base on a round surface.  The tikkas are a flat rail so they don't  need lapping.  The remington 700's mount on a round surface.  If you imagine trying to drill a hole into a round piece of metal you will notice that the dril bit wanders ever so slightly and you may not be centered perfectly on the crown of the radius.  Small deviations in the screw hole angle and location cause issues on the rings and may require lapping.

Its not the rings or the bases.  They are machined pretty precise.

That makes sense!.

I have not but I've been reading about them for years and contemplating switching all my rifles over to them. A lot of very knowledgeable people swear by them. I have a brand new Bushnell 4200 scope that when I get around to mounting it I think I will use the Burris rings.

for One mounting ring set. There are some for more and some for less on the web.

and how many scopes do I have mounted??? 

Maybe if we bought one lapping kit and passed it around---------Hum!!! that would be an idea.

I have a lapping tool and used to use it until I started using Talley rings and Burris . I only use Burris if I need the tapered inserts to gain more elevation adjustment in a scope.

I bought the kit from midway. Lapped all my rings. Did i see a difference no.

I lap my rings, and have never noticed a problem.  I'm not saying a night and day difference, but if I lap them, at least I know that I'm gaining on the coverage of my ring on my scope.  Maybe a confidence reinforcer for me at the range.

You may never see a difference.  It might pay you back if you accidently drop your gun on the rocks or drop it on the scope and it doesn't move where it could have moved with minimal scope to ring contact.

I do know that lapping the rings gives you straight scope tube alignment.  Torque or tension is not your friend when it comes to accuracy. Lapping greatly reduces that torque.

I never thought of that Haugenna. Good point
