Blaster B Pipe Question

[W8kski]

Are there any issues with using a Superjet chamber on a Factory B Pipe versus a standard Blaster chamber that is shaped differently on a Blaster? Also the one I am looking at has the stinger welded shut? Is that normal when using a superjet chamber on a Blaster?

Got my question answered. The older Factory Pipe looks different than the later model one for the Blaster. That's why I was confused.
