Tracked this beauty down last year finally, Beeman R1 with factory Field Target stock .177 Opened it up to find what appears to be a Laser kit installed. I de-greased, polished and Moly lubed everything including the trigger. I mounted a nice Beeman Blue Ribbon 68R 4-12 as well as Beeman double adjustable mounts to complete a nice rare vintage setup. It's making nearly 18fpe with AA 10gr pellets and is very comfortable with its adjustable check piece and recoil pad, accurate too.
