A better scope ring alignment tool

[pandm]

Makes perfect sense to me.

in part:
My scope ring alignment bars work differently. They are flat on the ends. That’s the missing element in the pointed bars. If you look at Photo, below left, you will readily see that the bars actually are a three dimensional projection of each ring “hole”. You’re looking at a solid representation of the hole through the ring. Put one bar in each ring and you can then compare the “holes” to each other. Comparing the “holes” is comparing the axes of those holes, the axial alignment. If the ends match and are flat together you have reconstructed the bars into one and the alignment is PERFECT. (Photo, below right) That’s it! An exact, true, three dimensional look at what’s going on with the receiver, bases and rings. “Dirt simple and deadly accurate.”

Study up and let's mount my scope.

I ended up bore sighting at 100yards my last scope. In hindsight I should have done it at 50, but what the heck. I was about 18-24 inches off center and it took me a few rounds to figure it out. On the 50 line I'd have wasted less ammo and been 8-12 inches off - a little more manageable.

I tried one of those cheap laser 308 round things once. What a gimmick, useless for me. It actually got stuck in the chamber and then the batteries ran out super quick. Never again.

DrBrianDDS Probably a few folk here willing to help you bore sight this in, including myself, always glad to help.

The device PandM posted about is to make sure scope rings are aligned, not for sigthing.

Whoops.

Mounted tons of scopes using nothing more than a 1" piece of scrap steel tube laid on the bottom rings. Never had a scope fail. Don't lap either. Just use electrical tape where the ring contacts the scope and tighten. Never had slippage or scope damage.

Ditto Grif.
But as I get blinder and the investment in rifles and optics has increased to stupidville, every little edge I can come up is a plus.
I don't own the above product but I'd be happy to give it a lash.
Currently using a 34mm tube and I'm just too damn cheap to buy the setup as I have designs on a 30mm tube unit next.
I'd love to learn of a local smith that uses this kind of precision in their work though.

I read this when mounting split rings in my Remington 700 and I made a pair out of 6061 I had in stock. Mounted the rings and had 100% perfect alignment.

I have not used them since and may have even used them for another project. It made me feel good though.

For hunting rifles I lap in the bottom rings with 600 grit abrasive and a lapping tool. For the match and tactical guns I either use a spuhr mount or rings that are machined at the same time.
