If somebody already knows that this is not possible without serious machining save your time and dont bother reading the rest of my long post, just let me know that it can't be done.
Otherwise.....I have a 1377 - personal trigger mod, steel breech, 24 inch 1760 barrel, 1399 stock. I have been considering buying a disco but the plastic trigger turns me off and alot of the part numbers seem to coincide with parts that I already own(the 1377).
I understand that I'd need the disco valve and the disco tube. I also understand that Crosman is big on modularity and recycling parts as much as possible from one model to another. After spending some time with the schematics on crosmans website I'm wondering if the disco breech (1761-019) is only a different part number to allow for the sleeve that the disco sights attach to. Since I want a scope-only set up, would the steel breech that I currently have work?
So, long story short, can the trigger assembly from a 1377, the 1399 stock, a 24 inch 1760 barrel, and the steel breech kit (1377sbpk), be turned into a functional disco with the additional purchase of the disco valve, disco tube(and associated parts-fill adapter, gauge port, cap assembly)?
With the 1377's and disco's sears and hammer pins sharing part numbers, it seems like it would work, as long as the two screws that attach the trigger assemblys are equal distance apart.....will that be a strong enough connection since the disco uses a "lug"?
Next question, if it can work my mental imagery is coming up with no forarm on this frankenbeast. So, is there some way to plug the hole for the gauge in an inconspicuous manner to avoid having an unprotected gauge (in this case I would rely on the hand pump valve to ensure not exceeding the 2k psi rating)?
(I also understand that there are other parts involved (different striker, barrel band, etc. but if the above answers are positive then its pretty obvious that the other parts will/should work)

I have a design done for the airgun you are talking about. It will require a little more then you realize. I have the parts about half built for the design as well. But I haven't worked on it for awhile. I'm in the process of ramping my production back up for my parts. I would recommend just getting a disco and installing a aftermarket trigger as well.
