Mounting/lapping a scope

[grundy53]

I recommend getting a tool like this:

You can tighten screws to the proper torque setting without stripping them from overtightening. When set to the proper tightness I have never had a screw work loose.

not too mention you can damage your scope tube and effect accuracy by over torquing.

Potterfield and his son have some good YouTube videos on scope lapping and mounting, check 'em out.

Talley lightweight scope mounts are 25 pounds for the base and 20 for the ring part Max

I learned about this the hard way. I tell any new gun owner that will listen about doing this because no one told me.

Deadnutz one piece mounts do not require lapping.
I love mine.

I always lap my rings even if its just a little bit. I use a lapping alignment kit made by kokopelli products. With their alignment bars its really easy to tell if the rings are out of alignment. The 2 pointed "alignment" bars wheeler sells are a joke. Lapping not only asures that your rings are aligned but also asures they are perfectly round. I've been using talley rings on my hunting rifles and have some seekins rings on a heavier gun. I always epoxy my bases to the reciever. With lapping you will never get ring marks on a scope as well.

I want to remount my scope using correct specs on torque for all scope rings and also make sure my gun is level and scope is level. I'm pretty sure I have it dang close but not perfect. Either I want to buy a gun vise and level kit or have a really good gun smith do it. Any suggestions would be appreciated.

I've never lapped a scope before btw. Was just looking at a wheeler scope mounting kit and a Tipton best gun vise to start

How accurate is your current setup?

Pretty damn accurate but I never shoot past 100 yards really but i hit bullseye on target which is probably 1.5x1.5 inch. Just want to start shooting out at 300 and stuff and know how any little thing can make the bullet hit left and right if the scope is tilted. Idk though talked to a gun smith guy earlier he said sounds fine as it is.

My range I go to only goes out to 125 yards.

The leupold dual dovetail rings needed the lapping bar to get perfectly aligned tho they say no lapping required.  In theory rings with micro grooves may lock onto thin tubed scopes better before lapping off the grooves but I prefer lapping just to ensure alignment and at least 2/3 contact,.

Exactly....that's all I use except for a couple period correct mountings on older rifles.  Try them, you'll like em.

I found some for Kimber 84m. You think they are better then the talley lightweights? I like the idea of a one piece. Less room for error. I really want to get my gun perfectly level with perfectly level scope and see what it will do finally. Eye balled the lAst time I mounted it.

I challenge anyone to conduct a scientific accuracy comparison of before/ after all this lapping minutia is performed on a hunting rig and show the difference it made in group size. Lapping quality scope rings on a hunting rifle is akin to mounting electronic fuel injection on a lawn mower. Alignment of scope rings so the scope lays fully in the lower rings is certainly worthwhile. Proper and equal torque of the ring screws is also important.

Lapping rings on a quality made varmint or benchrest rifle may pay dividends, albeit tiny.

When you have a rig made for killing an animal with a 10" vital zone, trying to eke out .2" in group size (IF you are a good enough shooter to scientifically measure it) is just silly.

If your hunting rig is throwing patterns rather than groups, there are numerous other items to try resolving that will make a difference (barrel bedding, muzzle crowning, action bedding, etc.)

On a hunting rifle where you are not dialing the scope at all you're probably not going to notice a difference in accuracy.

You can't assume brand x of rings doesnt need lapped. They are mounted on the rifle which more so determines if they need lapped. You can have a perfect set of rings and mount them on a rifle with a not so perfect action.  they may need lapped. If you dont lap or check ring alignment, you're probably putting stress on the scope and action. Stress isnt good. You also run the risk of ring marks on your socpe. With lapped rings you're also less likely to have tracking problems.

rings aren't always a perfect fit to the action/base so when you tighten them down in can bring the rings out of round.

I always epoxy my bases down, use blue loctite and lap. One less thing to worry about.

Agree with 3584 elk.  I do lap, but have not noticed any difference.  I've never taken off more than half the anodizing and that is measured in ten thousandths of an inch so I can't see that making enough difference at the target to measure.   Not an engineer, but lapping, I think, would make the front and back ring concentric to itself, but not necessarily the bore.  Having said all that I do lap because I don't think it can hurt and I'd rather tinker with guns than watch TV.

[thinkingman]

IMHO, lapping is more about reducing or eliminating stresses in the scope that lead to failure, rather than accuracy gains.
If I had a R700, I'd definitely lap.
No telling how screwed up the mounting holes might be.
