WHen did Crosman add the square breech with Scope Grooves?
†WOW I haven't noticed this on any 392's† yet! I wish mine had the breechblock because I simply hate the flimsy Crosman 2 piece mounts!
†I finally bought a Williams Peep and installed it in order to get to use some of the†pinpoint accuracy that the 392's have! Now 30 yard groups are ragged one holers with Crosman Premieres.
