tx 200

(1/1)

grandad:
I have been loosing velocity down to 770fps with 177 cp 7.9 pellet with the fac model. So I stripped it down for a re lube and seal change.When I pulled the o rings out of the breech the transfer port came out with the rings. I always thought that it was a one piece drilled into the end comp nut,But not so.
Should I lock tite it back in again and do you think that is why I was loosing velocity, I have ordered a new spring Thought it was that. Steve!

Jay308:
Hopefully someone will chime in on a fix.  It looked like a press fit, when I de-greased everything.  Air would bypass around the tube if loose and decrease fps. 

Loctite 620 is made for this application but not sure if it would work.

Jim-in-UK:
The TX200 transfer port is indeed an interference (press) fit, and replacing it using a dab of locktite should keep it in place.
