.22 LR front sight off-center?

Hello,

While doing my first cleaning of my Ross 1912 Cadet Trainer .22 LR, I noticed that the front sight looked a bit off. The gunsmith had said when it was checked out that it looked like one of the previous owners had damaged the crown, so I'm a bit concerned that the front sight got knocked askew as well.

How would I adjust it back into position, if it is possible?

It may be that way on purpose. Best to shoot it and see where it prints before you do anything. If it needs adjustment, it's in a dovetail so it must be drifted carefully to move it with a punch and hammer. Mark it first to monitor movement.

Thanks for the help! I'll hold off on doing anything until I (hopefully) get a replacement rear sight from another rifle I found online and then can test it all together.
 
Shoot it first to check and if you have to drift the front sight remember to move the front sight in the direction (toward) the point of impact. This will cause the barrel to move back the point of impact in the direction you want to go. Mark the sight and barrel with a witness mark before drifting so you know how much it shifted.

A little movement makes a big difference so go in small increments. It takes a good healthy wack to move the front sight so I wouldn't be surprised if it has not shifted at all.

It looks like the outside of the barrel is worn but the actual crown close to the edge of the rifling seems OK. Good Luck!!
 
Back in the day, with iron sights - move the REAR sight in the direction that you want the group to move - up/down/left/right. Do the OPPOSITE for front sight - if you want group to move left, then drift front sight to right - and so on. For illustrative purposes, assume that your iron sights are 24" (2 feet) apart - that would mean a movement of the sight will cause the group to move 150 times that much at 100 yards - so if you want 1" group movement - is a very tiny amount of sight movement wanted - 1 x one hundred and fiftieths of an inch to move sight to get 1" group movement at 100 yards. If your sights actually measure a different distance apart - similar rationale involved, except more difficult to explain.

Another thought - some elder ex-military rifles had rear sight unable to go left/right - only up or down - so "sighting in" had to be done by drifting front sight - I think. but do not know, that there was a standard about how far a front sight could be moved, before the rifle was rejected. But, so long as the front sight is "lined up" with the rear sight, you are going to get good groups - at least at one distance. I had a Schultz and Larsen "free rifle" in .22 Long Rifle - the front peep sight was deliberately mounted circa 3/8" to one side of the bore - the rear aperture sight was similarly offset - that rifle was meant to compete at 50 meter distance only. so, you "sighted in" for both windage convergence and elevation convergence. So you might be able to set the front sight where it looks right to you - but that is assuming that you are able to adjust the rear sight for windage - some ex-military rear sights were NOT made to do that.

If your gun is wonky - is up to you - do you want it to "look good" or to shoot groups where you aim it?
