2 piece base and Lap your rings. Problem solved.

But I bed them as well.......because I'm a tinkerer and a perfectionist

See, I don't think lapping the rings fixes misalignment, if they are out of alignment, I think lapping would fix the stress problem, but create another problem in that now the rings are ground out crooked. Don't get me wrong, laying rings that are aligned properly is a good thing as it ensures that the bore of the rings are perfectly cylindrical so they get the best, most even clamping possible, but if they aren't lined up, you end up doing the opposite in my opinion.

Just to quantify how far out of alignment I'm talking about, a flat rail, that I verified was flat, screwed down snug onto the front action bridge, well routinely leave enough gap between the rear action bridge and the mating rail surface that I can slide at least one and sometimes two business cards between them. So, with a two piece base, the rear ring might be 1/16" lower? IDK, I've never figured out how to measure it, but how do you catch that or fix it, unless you have a one piece base?

I'm not even going to discuss the fact that the mating surfaces have to be machined to the exact same dimensions (radius) as the action, and they rarely are. I had a rain that I removed from an action that you could see two scuff marks where it touched the action in front and one in back, so it was riding the action like a tripod. If you bed the base, you fix that, but I can't figure out how to bed a two piece base.

Shoot open sights!lol Bam! Prollem solved!

Maybe at bow hunting range.

Not only are they perfectly cylindrical they are perfectly in line with each other because you lap both at once.

I feel like leupold quality has gone to crap. I have dealt with machining issues on rear windage adjust rings twice in the last week. They mount up crooked. I now buy burris signature rings with posalign inserts to eliminate stress issues in alignment problems. I also like the dual dovetails.

Only if they start out in line with each other. If the rear is lower than the front, the lapping bar is going to apply more pressure to the bottom rear edge and top front edge of each ring. This is an obvious exaggeration of the misalignment, but you can see that the lapping bar is only contacting the bottom rear edge and top front edge of each ring. Photos to come.

The wind age screw design is a poor design but Leupold quality is better than ever.

Luke just get a set of Talley lightweight 1 piece bases/rings and be done with it.

I think that's what I'll do most likely. Would have done so today if I could have found some locally, but I'm going to have to order them.

What Talley rings you looking for? Rem 700 1" Low? Academy had some the other day I looked.

This is exactly correct, in the beginning of the lapping process. Once you have lapped until you have 90%-100% clean up front to back on both front and rear rings then the "bores" of both rings are perfectly in line.

Yeah I think, those should clear a 42mm scope. My academy didn't have anything except the windage screw type and a couple of tactical rails.

I'll check the 2 South Austin stores today. They use to have them in stock regularly but guess they are getting rid of them.

Cool thanks. Hey maybe they are on clearance!
