I think, based upon it's serial number, my blue streak was made in 1972. I bought it as a teenager. I haven't shot it a lot but every once in awhile it comes out. I never liked the way I had to mount a scope on it so I recently bought a Williams peep sight. I had to drill and tap a couple 6x48 holes in the receiver and I got them a little slanted but they work fine. I like the peep sight a lot better. It is handier for pumping it and I seem to be getting decent accuracy. I hit a 2 inch swinging target three times in a row at 25 yards shortly before sending this. The front sight is nearly the same width as the target at this distance.
