[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.
