I have for sale a Beeman R1 in 177 cal . It is in pretty nice condition . Its been sitting in my safe for years . i croned it and the Beeman silver jet were at 820 fps . I think that that gun will shoot at about full power when new if it has a good cleaning and lube . I had sent it back to Beeman once that they installed a new power sping. Price is $400 plus shipping to CONUSA . This gun is over 35 years old . I bought it new with the optional power tune . It was my pride and joy back in the day . can call Greg 540-309-0826
