Why not put a want to buy add in classified, lots of people have an old long tube from doing a conversion to bottle I'm in washington also, north of Seattle and have said long tube from my avenger :>) DM me
The main reason they only have a 15 year life cycle in the US is because of hydro testing CF tanks taking them to 7500 psi with water cracks some of the fibres and after three test's they start to fail. CF tanks should only be tested with Acoustic Wave machines.
If you look up YT vids by Gregor K he recomends seating the pellets all the way for best accuracy I think Kelly at Krazcool agrees as he sent a pellet seating pen with my last gun purchase:):)
Yep and if they rattle in the mag a jam is moments away, I leave the loading gate open after loading and seating tip the gun up and rotate the cylinder if any fall out I remove them all and never use those pellets in the Huben K1 or GK1
I also have a Notos that also got the bottle treatment $30 plemun $ 120 drop block regulator $112 300 cc bottle $512 for gun plus addons still 800fps for 180 shots so bang for the buck the Chaser is hard to beat longer barrel better trigger They are both very accurate
