Scope ring lapping kit

Ron AKA said:
Sounds like you don't know what canting is. It is aggravated by the height the scope centerline is above the bore centerline. Every time I see a scope mounted like it is on a couple of step ladders I just think - "I hope they keep that sucker level.

No Ron, I know exactly what cant means, but thanks for the cartoon doodle.

You're correct in saying it is aggravated a larger distance from the bore centreline to the center of the reticle.

My point, that your missing, is that using a scope with a tiny little objective, slammed within a micron of the barrel, in order to limit that distance is a bandaid. Solve the actual problem and make damn sure the reticle is vertical in your rings. Then, you can use #########high rings if you are so inclined. Your lapping and bedding does F-all to accomplish that.

When you have an answer to my question about knowing that your action and rail are truly level, let us know. That'll be an actual contribution to this problem.

Cost? The height that a rail adds to a scope mount? Canting error?

Cost is the only thing I can see here being a factor, but again my time is money so unless one gets joy from the lapping effort and somehow finds it therapeutic, direct mount precison options are available.

But to each their own, if you're set up for it have at it, but to go through all the trouble and buying equip to mount a scope or two, I'll pass.

I have ATRS rings on 2 on my rigs. As per the post says .... no lapping required!

I have been chamnging out my rings and rails as I can afford to for the ATRS stuff. Nothing better in my opinion!
I have a lapping kit for sale, after buggering up a couple of sets of the cheaper rings I have had enough of buying budget rings and trying to make them precise.
Buy decent and move on. I would rather be shooting than messing around trying to make rings align as they should.

If you had read the link I posted you would realize that the purpose of the lapping to correct any significant misalignment between the front and rear rings, and make room for the epoxy. When you follow the procedure the rings will be aligned and fitted as perfectly as the scope you are mounting.

A 1" wooden dowel is not round Ron. Not even close and for that matter it is likely not really that close to 1" OD period. That is is my point. Why on earth would you use a ####e piece of wood to correct something that you want to be precise? I am pretty familiar with the concept of lapping in this context and a few others. Your advice to use wood is not really the best. That was my polite point and I will stick and stay on it.

And my point is that all you are trying to do is roughen up the surface of the rings to make sure the Devcon sticks well, and any high spots are relieved. The use of the dowel is not lap the rings into perfect lapped condition, but to prepare the rings for epoxy bedding. That is why I epoxy bed, instead of just lapping.

Thats too much effing around for very little gains. I rather drop 160$ on a quality set of ATRS rings and be done with it. Which is why all my rifles have them.

This is a garbage in garbage out scenario and breaks pretty much all of the universally accepted machinists practices. As a woodworker and machinist I would never do what you are suggesting. If it works for you I think that you got lucky. And that's not a bad thing but you can't count on luck for precision, at least not every time.

Anyone else cringe at the thought of Devcon touching there 2-3-4-5-6 thousand dollar optic?? Releasing agent or not, in my world, no f-Ing way.

To StrelokRussia,

I read your original post to be asking for an inexpensive solution to fitting scope rings. I provided you some low cost alternatives to consider. The usual crowd of instant internet experts, lined up to dis those suggestions, and instead proclaimed you needed to spend mega bucks on scope mounts and the scope instead. If you are now wondering what happens to your accuracy when you do a terrible thing like epoxy bedding, have a look at the groups below which were shot consecutively. If this level of accuracy is not good enough, I'm sure these same experts will have no trouble providing you with evidence as to how much better their solutions are. Good Luck! If you have any questions about how I do epoxy bedding, just PM me. I've written this thread off, and won't be checking back in...

Like this Ron??

You're arguing with the wrong guys.....I've tried to keep an open mind about you. That's done now.

Why TF are your targets pink?? Lemme guess, something to do with a certain wavelength from a solar flare on that day.....

Is Ashton Kutcher here somewhere?? I'm being punked, right???

Its good to have a little tube of Prussian/Hi-spot blue($5 at most industrial suppliers). Makes it easy to tell where things make contact and where they don't before deciding on a course of action or doing anything that didn't need done.

How does one do that??

You apply a very, very thin coat of blue to one part, then put it in contact with where its supposed to mate, and then take it off and see where the blue touched.
I use it fairly often while working on my guns and other stuff in the shop. Good to see how well you action sits in the bedding after it cured and such too.
Its also pretty good for putting a tiny dab of it on the nose piece of coworkers glasses, that stuff will spread pretty good :)
 
I've been on the receiving end of it a few times :(

really is a good little thing to have though, a little tube lasts a lifetime, dykem and a few others make it.
 
Hey Gunnee is that one of those weird bushnell targets where they aren't 1" squares?



I have some too, I spent 0.0 seconds of time lapping and bedding, just bolted on some NF rings and leveled everything, can't post up any load data as it's just factory ammo, and since one hole at 100 yards distance is only when sighting in, I'll show some 350 yard targets instead, going by my range finder give to take a yard or two, lying position in the back of my truck off a bipod and rear bag.

I'm not posting this as some self proclaimed expert, just showing I have pictures of groups too, I don't mark them and catalogue usually just take them to send to a buddy for a pat on the back lol.







 
I sent mine to my brother and buddy to gloat, but having them on hand for when I'm called an "internet expert" came in awfully handy.....

GGG

ps - also bipod and bag....šŸ˜‰

pss - what the hell is up with those squares?? That's not an MOA, or an inch (i know, thank you cpt obvious), or .2MRAD (its close though, at 100M) . What is that??
