Just completely unscrew and remove the turrets. Removing the right angle pin de- clicks the turret. When the knob is rotated under it the dimple snaps clicks over notches formed in the top of the knob. The flat disk has a small detent dimple impressed close to the edge. Since, due to the right-angle pin, the bottom end of the turret assembly cannot rotate, the flat disk cannot rotate.
Through the center of the threaded section, the bottom end of the turret assembly is directly connected to a thin round flat disk resting on top of the knob. When functioning as originally designed, as the knob and threaded section of the turret is rotated during adjustments, the pin holds the bottom end from turning while sliding up and down as necessary in a slot in the turret housing. A right-angle pin is installed into a hole in the bottom end of each turret assembly. Together they apply the necessary force to hold the scope body firmly against the two adjustable turrets. By the way, the spring and plunger pictured to the left of the mount reside in the lower left cavity of the mount.
Unertl Mounts First, allow me to make the following very clear. Some Lyman turrets utilize a more complicated design but can be de-clicked. Unertl scope mounts are relatively easy to de-click. Unertl and Fecker mounts are very similar, but with some turret design differences. The problem is most of the vintage scope mount turrets are click adjustable. Fecker, Unertl and Lyman brand vintage scopes and mounts are also used for BPCR competition, especially since they can be found for several hundred dollars less than the modern brands. Although there are a few modern manufacturers of new legal scopes with non-click mounts such as Hi-Lux Leatherwood, Montana Vintage Arms and D.Īrms to name three, vintage R. Also, there is a group on Yahoo for Unertl telescopes.TexasMac's Web Site. Sometimes other center distances of the block flycuts or mounting points are desired or encountered. This results in a movement of the scope reticle of one quarter of an inch at yards, sometimes called a quarter of a minute of angle. Scope blocks are most frequently spaced such that the block flycuts or mounting points are 7. Adjustable scope mounts are threaded the same as a micrometer caliper, 40 threads per inch. Going from a 5X scope to 20X scope ought to help. I am hoping to get to the range today if the weather holds and see how much of improvement the new optics make. It goes to show that things did not change much from when my rifle was probably put together. If every shot counts and sighter target is not available best write it down.
Of course shooting all kinds of competition almost all rifles are different, direction of turn can be a major problem. Trouble with 9 is you get unorthodox clicks. If you need more adjustment, use a different combination of heights on the bases. I like the 9" spacing of the blocks because there's less 'scope hanging out of the bases on each end. You can work the formula to solve sight radius, range of adjustment available, scope block or sight height problems etc. There are three kinds of men: The ones that learn by reading, the few who learn by observation, and the rest who have to pee on the electric fence and find out for themselves. One other consideration, when you space the bases out further, you use up the allowable range of adjustment faster. Ever want to sell it anything else would be a negative Boats. Unless you are doing something special like a bench only outfit 7.
#UNERTL SCOPE BASE CHART HOW TO#
Also has the instructions on how to set up any model of Unertl Scope, including your 1. But, I think Unertl also published a chart that told you depending on the spacing of the mounting blocks how it effected the point of impact, etc. Ok, does anyone have the reference table for the mount spacing for Unertl Target telescopes.
