Urban Ops Barrel
thingiverse
Are you in a country where you can't get Chinese National Standard (CNS) PVC tubing? So am I! So I created this barrel alternative for the JSPB Urban Ops (Lite or 1337). The barrel fits loosely in the muzzle/head of the blaster before you apply the SCAR "zlin" rifling. After you apply the fishing line and tape, it fits perfectly. If you're opting to not use rifling with this barrel, I suggest wrapping a few pieces of scotch tape around the outside so it fits snugly in your O-rings. I'll be updating this THING soon with a link to my guide-to-build-urbanops-as-an-american AND a STL for the blaster pressure chamber (also originally CNS PVC), because the information provided on jspb3d.com for this build is not Home Depot friendly. Link to Urban Ops blaster STL and info: https://www.jspb3d.com/urban-ops.html FYI the barrel is 4 inches, a half inch can be sawed off to fit flush with the muzzle.
