Installed a MOJO aperture sight on mine a year or so ago and just got out shooting with it. In order to hit what I'm aiming at the MOJO rear has to be WAYYYY over to the right. I tried, to no avail, to tap the front sight over to the left with a dowel, but stopped when I felt I was starting really swing. Anyone know if this model front sight is MOVEABLE....STAKED...or what?
