    No, you cannot have a firing chamber made of plastic, unless you use engineering grade plastics, in which case, it’s cheaper to just buy a gun, not like they are expensive or difficult to get.

      You just bore out the barrel insert to receive the casing then reinforce it with 100% infill in petg or nylon. It’s not a perfect solution but my experiments last about 100 rounds before things get loose. I’m eyeballing injecting epoxy into low infill models next.
