Repro bracket, original No4T

[Hal O'Peridol]

What a pain in the butt. Went out to sight in my rifle. ARRRRGGGGGGHHHHHHH!

Luckily enough windage adjustment was not two bad, just 2 clicks left.

But elevation............................at 100 yds the rounds were hitting 16 inches below POA.

Now to try to figure out where to adjust the bracket. Not gonna touch the original rifle.

Hal O. P: Did you try zeroing it at 100 yards anyway to see how far it would move the cross-hair/ post down in the view? I had the same problem on a fake "T" but was able to make a significant correction (raising the rear of the bracket) by hand filing the lower bevel on the bracket. Of course, with each small bit removed there, it also changed the lateral alignment (by pulling the rear of the bracket closer to the pad) requiring more filing on the boss that seats against the front pad. Tedious work but I was able to get it near perfect such that at 200 or 300 yards the cross hair is just a bit below center in the view- similar to the appearance in the view on my real "T" with matching bracket. After about 200 trips between the garage and my kitchen table with view of DAP I called it finished to avoid pulling out any remaining hair. Good luck with yours!

One way you can make some adjustments for range collimation error is to lift the front or rear of the telescope slightly in the telescope bracket/cradle by using, say .015" brass shim in/around the bottom third of the cradle. Never done it myself but theoretically it MUST work as you are in effect lifting the grat post (which is a foresight isn't it?) by shimming the front cradle or lowering the grat, to a much lesser extent, by shimming the rear cradle. But rememberto just nip the taper lock cradle cap screws down until they bite and don't overdo it
