Re: how do l remove the rear iron sight?
There could be a few reasons. Look to see if there is a dovetail that the sight sets in. It would be a matter of tapping the rear sight off with a hammer and punch. If no grove is found, then it may have been epoxied to the barrel. You may again have to tap on it a litte to knock it loose. You don't want to pound on this stuff with a 3LB. sledge, just light taps to see if things move. If nothing happens, then take it to a qualified individual that knows what they are doing.
