Interesting way to See How Scope Contacts Rings

[BoydAllen]

It is not that often that I come across something rifle related that is entirely new to me. This was, and I thought it worth sharing. Let me know what you think.

Boyd, I first saw that described by Norman E. Johnson in the mid '90's. It's a good visual aid. Also a good way to check reciever to bedding contact. -Al

Al, I should have known you would be ahead of me on this. I hope your Christmas was good.

I just got a new Schmidt 6x36 to try.
I was reading through the manual and came across an odd suggestion.
They say to cut section of Latex Glove to put between the scope and rings. Didn't do it, but made me think about it. Then I thought, what do they know anyhow

I learned about this back in mid 80's when a gunsmith friend told me about checking ring and scope tube contact. I've lapped every set of rings since then. It isn't so much the rings it's the receiver you're mounting it on. I have found those picatinny one piece rails to be really wacky. Bed the rail first and then check ring contact.

If a person beds the bases, and then puts two "stripes" of 10 mil tape at 4:00/8:00 in the rings, to support the scope, followed by original JB Weld...

Pretty good contact.

JB is smoother than the various other epoxies I use, and plenty strong enough for this task, while having enough viscosity to stay put in the ring until it cures.

Edit: I do also lap some rings, but anything with high recoil, misaligment, and/or high value scopes gets the epoxy.

I'd add two strips at 10 and 2 on the top half but lapping will envelop the entire tube. Best for high recoil. Note I've been seeing a lot of bases with screws that are too long on the front. Check screw contact especially on the front screw that may contact the barrel screw threads and screw up your base bedding job.

What will the contact on the rings reveal when attached to a rail that sits atop an action, as opposed to a precision block?

As with many things, the concern over ring alignment and how a scope sits in those rings has been discussed over, and over again. The fact is every part has a certain degree of built in tolerances.

If one is going to check for a high percentage of ring contact, you should do it with the rail or mounts bolted to the action and the scope you are going to use checked in those rings.

this is what i was thinking- it tells me nothing showing the ring contact when the base is settting on a block of metal on the bench. if Im gonna bed or lap rings to a scope it will be on the gun im going to use the scope on.

Boyd - i use to lap rings. since ive started using the burris sig zee rings with the inserts i dont use much else. the burris rings look a little flimsy/ chincy to me but i have to say i dont think ive ever had a scope move in them and ive used some pretty big scopes in them like an NF br ect. the plastic inserts really grip and form to the scope. i have to say i havent used them with say a 300 win mag or a 338 lapua either though.

Ah, right.
I hadn't thought of that.
It does make me feel better now because I'm using mounts with the rings built in and the mounts have only 1 lever [Bobro]

I agree. What the video does show is that even with a precision base, the contact was imperfect.

If you think the Signature Zee rings may be a little flimsy then take a look at these.

I basically agree. One thing I've always wondered about. We can lap rings with a lapping bar with the rings installed on a base bedded to the action.

Now. What about the scope profile? Can't do much about that.....

So to sum it up, have I missed any pointers about how to evaluate a scope profile? I doubt they're all perfect. No matter the cost.

they havent been flimsy in my experience but they look it. lots of so called premium rings dont look like there is much to them. ive seen these rings youre showing - was always to cheap to buy some since the normal ones work. thanks

That's some nice directing and nice montage!

Bed the scope tube to the rings. -Al

These are what I use. They come with 40 moa of inserts and that's more than most scopes can handle.

 

[AlNyhus]

The Burris Signature inserts do a great job of conforming to the scope tube. It's too bad they don't make an aluminum version and a version for the Davidson/Kelbly style dovetails. -Al

As crappy as rings are do you even have to check?
