HELP with 1377

Trophyhunter49 · October 05, 2012, 11:46:52 PM

I have been workin on my sons 1377. When you shoot it you can feel air that come from under the breech. I put in a new breech seal and a new bolt seal and still feel air!! Any ideas!!!

Make sure your barrel and valve is lined up with the breech seal also did you put the breech screw back in and is it tight. sometimes the barrel will twist and not line up right.

Mike is right. Check that the transfer tube is fitting into the barrel port. I ususally center the barrel port on the breech and lightly snug the barrel set screw. Just as I marry the breech to the pump tube, I will loosenn the set screw so I can wiggle the assembly together. Also, remember that the shorter part of the transfer tube fits into the valve exhaust port.

which variant is it?

Does the valve build pressure and hold air?

It builds persure and holds air. iT JUST BLOWS AIR WHEN YOU SHOOT IT? I THINK IT IS MAYBE A PHASE 3

What's the first four digits of serieal number?

Find an adjustable flame; disposable lighter. Unscrew the adjustable flame valve and remove the o-ring. Use this o-ring as a top seal on the transfer sleeve.

It's the o-ring on the left.
