ditto; Track.
Be aware, fixed sights can only be adjusted with a file.(front and back)
And, fixed sights require confidance in all of the prb variables.
An understanding of how to change those variables is as important to fixed sight use today,,as it was then.
Example,I ran out of cloth, had ta git new.. now my point of impact is just a ""littttle bit low,,and a tad right"",,,,,,,
How do I know that? I shoot alot. here's my point, I'm not going to file the front,,nore peen the rear to the side for "a bit" of cloth. I might just raise the charge a bit,,or ,,,,,,anyways luck to ya
