G'day Carl. If it is dovetailed into the barrel you need to drift it out sideways, either way, don't matter. Use a brass drift or a small wooden dowel.ausjackal said:sorry for posting this question in two areas... I have just picked up my 336BL this morning and I have a set of Skinner Tac Sights on order. Can anyone tell me if and how you remove the existing rear sight?
