I am looking for mainly just the rear night/fiber optic sight portion for this pistol. Friend does not want to spend a lot of money on these sights as the pistol is just a beater/cheapo pistol to him. I have seen the Dawson sights, but figured there has to be some other company manufacturing...

Installed a red dot sight on my ar 15 decided in a emergency situation it was to much trouble went through my junk and found a 1.5x4.5 scope. Mounted the scope with the rings I had and it was much to low. Ordered a 3/4 inch riser and bingo it was ideal. Now the problem is I can't bore sight it...
