And I put it back together and the barrel was completly airtight and the dart shot about three feet. I used about 1 foot of Sch. 80 PVC pipe with stock taggers and even added a recon spring. Here are soome pictures.

Here is the entire assembly.

The springs nested together

The seal and the other peice

The barrel and the glue with the dart stopper

And lastly where the glue and barrel end.
If you can help i would greatly appricate It.
