Little Adjustments

[Sean Gadhar]

Getting set for fall, I replaced my rear sight, in the hope I could gain 5-10 more yards with my Flinter .54 cal ESR, added a Davide Pedersoli rear sight. . .but now my front sight is too low, so I'm rough fitting a new cast brass sight to see if that will fix me back up.

Could you not file the notch in the rear sight lower to raise the impact point up?

Uh...no!

got to go up on rear sight to raise elevation

If his front sight is too low, the gun is already shooting high.

Replacing the front sight is a much better choice.

Filing the rear notch alone won't bring the group up. But filing the top edge lower, and one will probably have to make the notch deeper, will bring the group up. I had to do this with my smoothrifle, the front sight being soldered on.

 

[Sidney Smith]

Uh...no!

Really. If he's got too low a front sight, and he files the rear sight down he will get to a point where the sight picture should allow him to get a more dead on aim. If he were not going to touch the front sight then yes, a taller rear sight would bring up the group. I'm not talking filing the rear sight so low that it causes him to aim lower. But if you start out with too tall sights or two short ones, you should be able to get the same result.

To move point of impact downward, one should either add material to the front sight or remove material from the rear sight. Conversely, adding material to the rear sight or removing it from the front sight moves the point of impact upward.

Wow, interesting Sean, you got 7 posts with advice how to adjust.

I've always found those rear buck-horn to be a PITA.
Sure, all that crap about "low_light" situations,, but honest, the front post is supposed to line up with something??
It all depends on your sight picture,,
How do you center that front post in the back with your eyes?

suggesting a type of sight or manufacture is advise, when adjusting sights there is only one way
From Custom Turret Systems
If your bullets punch too far to the left of the bullseye, then move the rear sight to the right. If the point of impact is too far to the right, then move the rear sight to the left. The rule is the same for both vertical and lateral adjustments. Just move the rear sight in the same direction you want to move the point of impact.

That would make the weapon shoot even lower. You raise the rear sight to get higher on the target.

FORS

Front Opposite,Rear Same….

but now my front sight is too low,

"Front sight is too low,,,,,"
The gun is shooting too high....

And as I said, just filing the notch won't (or shouldn't with proper sight picture) change point of impact.

Always remember if you raise the rear sight the bullets will shoot higher if you lower the rear sight your bullets will shoot lower! I wouldn't dare try to explain why. It is easier for you to pick up the rifle and get a picture of what is happening.

I, totally understand that....
The rifle is shooting too high as evidenced by the o.p. stating the front sight is too low....
Yet we have a bunch of people here giving advice that will make it shoot higher,,, or,,,, have no effect at all...

Unless someone is lining up the top of the rear sight with, the bottom of the rear sight notch,,,, HOW THE HECK IS MAKING THE NOTCH DEEPER GOING TO EFFECT ANYTHING?!

Filing the top edge of the rear sight however will have the effect of lowering it,,,, thus lowering the point of impact.
This rear sight was probably a little over a 16th of an inch taller when I started filing it, I don't remember the measurement,,, but, filing the entire rear sight lower brought my group down about 6 inches by the time I was done.

Your first post said "File the notch deeper to lower impact" that would make the impact higher! If you don't understand stop what you are doing and get some help before you ruin your rifle!

Broken, there’s a lot of us that shoot with the front bead …. Bedded in the rear notch.. Sunset position.

LME, filing sights won’t ruin your rifle… it could cause you to have too but more sights however.

It isn't my rifle,,,,, and filing the notch in the rear sight will not make the gun shoot higher.. Filing the notch alone will not do anything.

But, thanks for catching my typo. Unfortunately it is too late to edit that 1st post. I did mean filing, the entire, rear sight will lower the group,,,, which I think I covered in follow up posts.
It was a typo though so thanks for catching it.

First, for those of you who got it backwards, don't feel bad. I have been at the range more than once holding a file in my hand staring off in space trying to be sure I file the front sight to bring point of aim up.

As to filing the rear sight . . . this is my rear sight

So for me, as I get older I like the buck-horn, but I couldn't say why. Something about it allows me to deal with my old eyes trying to adjust

I like the front post to fill that little notch, making a flat plan with a brass center, then a 6 O'clock hold. . .so something like
