I have a Bushmaster ORC. It comes with the milled gas block.
I managed to find one of the elusive Bushy/YHM flip front sights that clamshells around the gas block. I leveled the rifle and then leveled the front sight before tightening the mounting screws. When I sighted it in, I had to move the rear sight windage WAY to the right....almost using up all the travel. If I wanted the rear sight more centered, should I move the front to the right? |
| Page 0015-16 of TM 9-1005-319-23&P shows how to go about aligning the front and rear sights in order to limit excessive windage. |
