"Drifting" the rear right

[jtmattison]

As most of you know I just got my new GPR.
After lapping the barrel she is shooting a real nice group but it is a little left.
I am worried about drifting the rear sight to the right in fear of ir popping out of the dovetail.
How much do you all think I can move it right before it will come out of the dovetail?
Just wondering if anyone has experience with it.
On my Trade Rifle it didn't take much to knock the rear sight out of the dovetail.

if you think you have to move it say an 1/8" try moving it 1/16" in the direction you have to....and move the front site the opp direction 1/16".....just a thought that might work so you are not moving it too far........................bob

I take a real fine felt tip and make a line from the sight on to the barrel. This give me a referance point. Then I would slightly tap the sight to the right, put a drop of lock tight on the sight an barrel edge, blow on it to dry it. Shot again, and repeat as needed untill you are happy with the sight. Then peen the dove tail to lock the sight. The felt tip and lock tight will clean off easy when you are done.

 

chances are that you will not have to move the sight as much as you think. It only takes a small movement of the rear sight to make any adjustment. The sight only has to move as much as the distance change at the sight, not at the target, and that will probably be less than the 1/16" sugested. Three inches on target is only a few hundreths at the sight.

In addition, most of the dovetails on factory guns are TIGHT. You will have to use a brass drift and a good hammer to move them at all. This is not a precision science. Smack it and shoot, smack it some more and shoot, smack it back where it was and shoot. The felt tip pin is a good idea, you wind up back where you were a lot of times.
If they seem too lose after the adjustment you can stake them. I have seen very few factory dovetails that I would fear poping the sight out, it usually takes a jackhammer to move them!
