The University of Delaware has HvZ. They meet frequently and have Z-week once a semester.
At UD they have mechanical engineers complete design projects every spring. The course load is heavy with a lot of dry math and science courses, so they do this to add some hands-on experience to the major.
They also have what's called a 4+1 plan in which you earn both a bachelor's and master's degree in 5 years.
It's kinda expensive if you're coming from out of state, though you might do well with financial aid and scholarships.
That fact that this can achieve 50ft ranges using a nitefinder tube and two mavericks springs is impressive. I wouldn't think such a setup would be able to deliver enough air to compensate for extra deadspace the brass breech might create.
This is a great proof of concept mod. A rev 2 of this mod could really bring some power to the recon-style blasters. I would suggest focusing on increasing the power and reinforcement of crucial parts such as the nf catch.
