I've been modding my Crosman 2250B slowly. So far, a Leapers scope, Crosman trigger shoe, pipe insulation cheek rest, and homemade barrel shroud. I hope to switch out the breech to a Crosman metal breech with the grooves so I can get rid of the hideous intermounts on the barrel. I might also shorten the 1399 stock because my 7 year old likes to shoot this carbine.
