Hello all,

I am wondering if it is at all possible to convert a 2260 from co2 to pcp by swapping main tube and valve assembly for the disco tube and its assembly.

Would a BNM breech that's made for a 22xx rifle work on the disco tube?

Easy peasy!
Just drill the two additional holes to retain the valve body. Create a new valve body neck that has o-rings to keep the air from passing by the valve. You can buy the new end cap that is threaded for a forester fitting. It is a simple as converting a 2240.

Short answer is yes. A disco tube and valve as well as the valve retaining screws ,the guage block complete and the fill plug .The bnm breech will mount with no problems. You will have to notch the hammer for the breech retaining screw. Easy peasy.
Depending on how much pressure you want to add to the tube , I would stick with the 2260 tube and the rear half of a disco valve with an extension to go past the stamped lettering in the tube.

Not quite done collecting
