If you don't lap there is no way to know how bad the fit is.
lots of rings say no need to lap, but they bolt to a base thats bolted to the action
I think it is almost common sense, if you have a lap bar to check all rings some need very little some will surprise you.
I can't believe a guy would spend several hundred bucks on a scope and not check with his lap bar.

I always lap my Burris Signature rings but you have to be careful because it's easy to take too much plastic off the inserts.

Re: How many of you lap your scope rings?

Varmint Hunter, you made me laugh. Thanks.

I lapped my dovetail Rings. I also have a DNZ 30MM Gamereaper mount and I didn't lap them per instructions not too.

For years I didn't bother doing it as I shot rather mild recoiling calibers (.35 Rem, .308, & .270 Win.) I started doing it with my magnums and knock on wood I have not had any shift in zero on those rifles.

Re: How many of you lap your scope rings?

On the serious side, I have a few tacticle ring & base set-ups that were lapped by my smith. However, I am now totally sold on the Burris Signature series (insert) rings. Properly installed, they can solve any alignment problems that may exist, can provide quite a bit of elevation, do not bind scope tubes, do not mar scope tubes, and have never slipped on any of my rifles that have them.

Re: How many of you lap your scope rings?

Reading this thread with interest. I've just ordered NF 20 MOA Picatinny base and Ti alloy rings for my NSX going on a Sendero. I've read some posts that said NF rings on NF bases probably dont need lapping which is something I want to avoid if possible.

I want to use the scope on one or two other rifles as well until I get rich enough to but more scopes If I have to lap the rings on one setup, where does that leave me in mounting on another rail on another rifle???

Re: How many of you lap your scope rings?

Only way I know of to find out how good a fit you have on any of your rifles with the scope base and lower ring halves installed would be to start the lapping process with a lapping bar and then look at the lower ring surface and see what % of contact is being made by the lapping bar.

I mounted scopes for many years without any lapping and I'm still alive. I know of no way to quantify how much lapping helps maintain scope consistency, or how much a lack of lapping hurts consistent performance. I'm convinced a lapped, full-contact fit is best. How bad of a fit you can get away with before you might start to see some inconsistencies? I couldn't pretend to know, and don't see how anyone could say. I know it takes so little time to lap, that I prefer not to risk this potential source of problems. But I'd still mount a scope and hunt with it if I had no way of lapping the scope rings in. At this point I'm pretty much set up to lap the rings and there's little reason not to.

A health analagy could be cancer or the flu. How does one ever know exactly what caused them? Or what combination of causes? Since I started lapping scope rings, I'm finding that most of them are off at least a little, and it generally doesn't take too much lapping to obtain 75% contact. I have had one set that was off quite a bit. I use Seekin's aluminum scope rings. I've never lapped a set of steel scope rings yet. I imagine steel would likely take a little more time and effort than my 7075 grade of aluminum.
