I just got a BSA martini international MK1 with a Parker Hale #25b rear sight on it. The rifle is great but the rear sight is kinda making me nuts. If I want to change the point of impact to the right I have to move the rear sight to the left which is just opposite of what one is supposed to do to adjust the windage of any rear sight. The elevation is normal in its movements just the windage is backwards. Iv'e been able to find out how many clicks per inch on line but nothing about the backwards windage adjustment. I was also able to find out there were several variations of the # 25 sight but nothing about its adjustment controls. Anybody out there know about this issue, is the b for backwards
