I took off the FSP and installed a Yankee-Hill gasblock/flip-up sight, and was wondering how far off center it was. I was intending on spending the better part of tomorrow's range session adjust the windage, when I had an thought.
I just happened to have a .223 laser bore sighter, so I loaded it up, set my rear sight at 0, loosened the bolts on the gas block, and aimed the rifle at a wall about 20 feet away. I then proceeded to gently tap the front sight tower in the appropriate direction until the sight post was centered on the laser dot. Once that was accomplished, I tightened the bolts up on the gas block, and I was zeroed for windage. Now, any further windage adjustment will be for actual wind and not to compensate for a canted sight tower.
A Sort of associated question - should I blue-loctite those gas block bolts?
