[dye29]

hi all so I have a RTI P3 and started leaking slowly down the barrel so I changed the ring inside breech block , new valve seat and oring also new valve but when ive installed the air gushes out of barrel now . so I reordered another valve and seat and new orings but same again why is this please .
I just can't get this to seal ok now any tips as all is new .

It has an air assisted valve. Mine was doing the same thing so I removed the valve and found the spring inside was in several pieces. I got a new spring from AOA after about 4 weeks.

Did you ever find the fix for your P-3. My P-3 is doing the same thing. I have about 300 shots through the gun.

Have you tried cocking the gun before filling with air, could be the hammer resting on the poppet shaft.

Can you go into this thought a little deeper? Cock the P-3 then fill to 300B and then release hammer manually or dry fire? Does this just need to be done once for his gun or every time? Cool trick just trying to learn. Thank you.
