I acquired a new production Crosman 2100.As ALL old parts were tossed in the dumpster, I need to know if the new parts from across the pond will be backward-compatable.I have not opened it up as yet. but have a few observations.1. The clearances between the forearm and the plastic "clam shells" at the pivot end have been opened up, quite a bit.2. The pump operation is not nearly as smooth as it used to was.......3. The pump rod is now ALL plastic; not all aluminum as the Legacy; not even half and half as it was in the U.S. made 2100's.4. The bolt is difficult to operate. It requires concerted effort to close, and once it is, the heel of the charging lever snaps into the slot very securely. So much so that it requires a manual depressing of the heel in order to allow cycling of the bolt. I mentioned this to Crosman and was advised that this is a common complaint, caused by over-tightening the receiver screws, pulling the receiver halves together and binding the bolt. However, I loosened them up and snugged them down lightly, and there was NO change in bolt operation. ..........That is as much as I know at present. More findings to come as I get inside the critter.
My experience with several Legacy 1000's and a 2020 production year 2100 is that the cocking handle is pretty stiff when new. They break in to be one finger operable with time.
I went ahead and did that bit of work to the bolt as well as swapped in my 2100 trigger components and removed a part that I could not for the life of me determine the purpose of.
