Kuharsky Bros. Scope Base

edited October 2010 in Ask the Experts
I recently boought a rifle that has a Kuharsky Bros. Scope Base mounted on it. I am needing to find out what type of scope rings will fit this base. It looks like a well made base that has windage and elevation adjustments built into the base. Any help would be appreciated.

    Uh, Kuharsky.

    This was the alternative mount for the Bausch & Lomb scopes with no internal adjustment.

    Certain Bausch & Lomb rings will fit the Kuharsky Bros. mount bases with adjustments. Take a look at GB Auction #183965750 for a picture of the type used. Long out of production, these can often be found used as well as new-old-stock on this and other auction sites. I have had several Kuharsky Bros. mounts, B&L rings, and B&L scopes over the years, still have a couple. There are two common lengths to the flat springs that hold them in place in the mount. The Kuharsky manufactured rings can have a spring-loaded plunger instead of flat spring, but they attach the same place and way.

    Hawk,
    I don't think Kuharsky Bros. ever made rings. I collect this stuff and I've never seen rings marked Kuharsky. Also, Stroebel's book says Kuharsky bases were made to take Bausch & Lomb ring sets. No wonder gibster is confused!

    Thanks for the info on the bases. Was this a good system and would the scopes hold their zero? How difficult is it to find a scope/ring set-up for this base? Thanks again for all the info.

    The ring assembly comes in two two types. The earlier type had a spring loaded plunger that was compressed to snap the ring assembly into the base. Later, and supposedly better, type had the flat spring and a nut to tighten the spring. The nut looked like a four bladed propeller. The advantage of the scopes was that you zeroed the base so a scope could be taken off one rifle and snapped onto another and would be zeroed for the second one. A good idea and I believe they held their zero but was obviously not a popular scope mount as they have been long out of production. The B & L bases are much more common than the Kuharsky. They show up very often on the internet auctions and at gun shows.

    Just for the record, I currently have a set of rings that were manufactured by Kuharsky Bros., Erie, PA, and came in Kuharsky boxes, though the rings themselves are not marked with the Kuharsky name. I think the two companies had a close relationship, with Kuharsky manufacturing many if not most of the bases for B&L, as well as some of the rings. The B&L external-adjustment scope mount system worked very well indeed in holding zero. As said, one could set up the mount, and change scopes from rifle to rifle and each rifle would be zeroed. The scopes and mounts were relatively expensive in their day, and very finely machined. Internal scope adjustments gradually became the system of choice for most hunters and shooters, so the B&L external adjustment system went by the wayside, despite its working well and even having some advantages in ruggedness and interchangeability.

    Kuharsky mounts were made for B&L external adjusted 1" diameter scopes back in the late 60's, early to mid 70's. They were mostly one piece design and could be used with the plunger type clamp rings or the leaf spring type. I used to be on the B&L development team and can tell you that plunger type clamp ring had swage problems. The leaf type clamp ring was significantly better and more reliable, especially with high recoil apps. Back in the day, the scope market was dominated by B&L, Refield and Leupold. Nobody came close to the quality that these 3 companies produced. The big problem with the other brands was their poor optical and mechanical designs. I have destroyed many Bushnell, Tasco scopes with the recoil from a 375 H&H rifle, which was our standard punishment gun that we used to test the competition and our designs. If you already have a pluger type clamp ring I can tell you how to test it to make sure that the zero won't shift, otherwise the leaf spring design is best.

    I own a couple of rifles with the Kuharsky external mounts and one scope with the flat spring/screw rings. I have used these rifles all over the country and have found the system to be extremely rugged. The rifles are different caliber and switching the scope between the two is not only easy but each time the rifles are back to zero. I have not experienced any zero shift in over thirty years of using this system. Other than availability of parts it is a great system. In fact, I am considering purchasing another set of rings to add another scope option. If you've got some, give me a shout, let's talk.
