Check out this system for scope mounting in conjuntion with dovetail and or, dual dovetail rings and bases. Really works slick.

Jerry sent me one of these for T&E. Pretty cool idea....

I see where he has applied for a patent, but haven't long pointed bars been around for a long time? All he has done is found an application for one. I mean, if I kill a snake with a hoe, can I patent it as a snake killer? Makes no sense to me although I do see where it would work. miles

Yes, slick. Looks better than using a lapping bar to do the same thing. E

The best thing a guy could do is ditch the twist in rings! LOL especially rear windage adjustable.

Wait a minute........That's kind've a take-off from the scope mounting kit with two pointy bars that pointed towards one another and you lined them up with the points almost touching.

I can recall thinking about buying those from Midway 25 years ago.........

"conceptual thought" is always where its at--

about 140 years ago a fellow bent a piece of wire into a loop--

it was well known that wire had been around for many a year...

today we know that "bent wire" as a paper clip.


(while i know it can't be agreed upon as to who really was responsible/and patent vs. no patent, etc. the above example illustrates conceptual thought to this type of issue).

Excellent! I made my own long pointy bar years ago (got the suggestion from a gunsmithing book-- maybe Jim Carmichael's book?).

Only the best will do for my mounting jobs!

... and here I thought it was a Talley thread <grin>...

It is amazing that I never heard of this device before today and I can attest to it's simple elegance and design. I bought a Cooper 17HMR from brassman here on the Campfire and needed to scope it.

I called George at the Powderhorn here in Bozeman and told him I needed some matte rings to go on a new Cooper I had bought. When I got there, Bill and I put the rifle in the vise and he pulled this instrument out and we proceeded to put the rings on the rifle.

Bill explained the principle on how it was designed and we put the rings in place and loaded the tool into the bottom rings. With a few adjustments, we tightened everything down, checking the center of the bolt and bore with the points on the tool. After everything was set to our satisfaction, we bore sighted the scope only to find it off-center about 5 clicks.

I took it to the range and was 2 inches left and about 3 inches high, more than satisfactory for a bore sighting. This tool does work and would be a valuable tool in any shooter's box that cares about easy, true alignment of their scopes.

Very interesting!

One thing many people don't realize about the common pair of pointy-tipped mounting bars is that just because the points of both bars align doesn't mean the rings are aligned. This is easily proven by taking two pencils and putting the points together. The angle of each pencil can vary considerably.

Paired mounting bars are much more accurate when the flat ends are matched up, rather than the points. If you use the points, it helps a lot to place a small straight-edge along the bars.

I just received some really interesting alignment bars (1" and 30mm) that have slots so the base screws can be tightened when the bottoms of the rings are in perfect alignment. I haven't used them much yet, but they hold a lot of promise.

Where did you get those alignment bars?

The last scope I mounted in Leupold dual dovetail rings I went cheap on the alignment tool.

I found a 3/8" drive deep Craftsman socket in my tool box that measured almost exactly 1". The problem was I only had one. My next door neighbor just happened to have another one that was the same.

With the two 1" od sockets and a straight edge it was easy as could be to be align the rings and mount the scope.

John,

I talked to Jerry about these bars, and he told me he has one with your name on it. I will get one from him and get it to you. They are a way to perfectly align the rings, I did it, so that has to be a testimonial of the simplicity of the bar...

Noticed that myself. The bars could be 90 degrees from each other, and still line up point to point. They actually work better if you flip them around flat side to flat side. That being said, a lapping bar works even better, and Burris Signatures work even better than that!

Shrapnel,

That would be great!

Agar426,

The bars came from a well-known custom gunsmith. He wants me to test them thoroughly before revealing anything else.

dogcatcher,

Burris Signatures are great!

I thought the same about the two pointy ends, and a light went on. The pencil analogy is a good one. I went with a couple of pieces of 1" drill rod, with the ends faced off smooth. One can also serve as a scope substitute for bedding the rings in epoxy.

And dittos on the Burris Signature rings.

I mounted my only set of dual dovetail rings without a bar or bars. I used my caliper and measured both sides at the area the screws go through the caps. It was very tedious but I got them aligned. My gunsmith looked at them later when I took the rifle to him to have the LOP shortened and said I did a good job and asked how I did it.

Thanks for the input! I've got a machinist friend of mine looking to make one for me, but I thought it may be easier to just buy one if they were available.....
