Is it as simple as punching out the two front sight pins and twisting/adjusting the front sight assembly by hand?

Should I punch back in the same two pins so long as they seem secure?    

If you drive the pins back in, the sight will go right back where it was.

Shishapangma, It's not a simple as that.


The sight is canted due to one of two things.

The first would be that the barrel slipped in the upper and the barrel extension pin has grooved the upper index slot, causing the barrel to be twisted in the upper.  Re-installing the barrel will solve the problem.

The second would be that the barrel extension/pin was not indexed with the front sight tower, and the extension/pin is correctly indexed in the upper receiver. This could be fixed by re-installing the barrel, if the index is not too far off. Or the front sight can be modified to use setscrew instead of the pins to index the sight back to zero.

Hope this helps.
