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.
