You could see what the Blue Book of Gun values has to say. Or, look at some of the main gun sales websites. Or see what your local gun store thinks. A lot will depend on what shape your rifle is in, if anything has been changed, etc. Just FYI, Browning's website (see link below) said the BAR MKII wasn't introduced until 1993.
