units to fit prewar BSA underlever air rifles and BSA Cadet Major and airsporter Mk1. Modified design with click adjustable elevation wheel and lock screw to prevent loss of zero. Blacked finish, will fit directly on to most BSA models, may need VERY SLIGHT filing on some examples due to the rifles sights originally being hand fitted when made!. Will also fit Diana Haenel and other rifles which originally had this design of rearsight. The sight measures 19.56mm (0.771”) across, to fit in grooves of 10.6mm (0.417 inches)


This design keeps the spirit of the orignal, while offering a very positive adjustment of zero point, making it ideal for vintage airgun shooters, shooting at different ranges.

Special care has been taken with the finish of this rearsight. We believe it to be superior to any other reproduction sight currently available.

Money back if you are not delighted.
