SG Nerf started a thread on the NerfSG forums with info on the R&D he'd been doing on a Brass Breech design (HERE) but all the vibrations/movement when firing caused the brass to smash itself to bits all the time.
This got me thinking that there had to be a way to make a breech with a 95% seal at least that was sturdy enough not to break all the time.
Here is the design I came up with...
And now for the actual thing. I kept the stock return spring in the same spot. I just wrapped the conduit with about 10 layers of e-tape to act as a spring rest.
Here is the bolt section. You can see how much of the stock bolt I left here. The 1/2" Brass fits nicely inside the PETG with 1 wrap of e-tape.
