Thanks for your reply


I am interested in creating full kits that use donor parts. Stuff like clam-shells for lower receivers, stocks and shrouds etc. I would also need to print some switches like mag releases, fire selector and some of the trigger mechanism. Basically all the stuff you could get away making with a polymer on a real firearm. Much of this will be held together with screws or pins. The reset of the items like barrel, bolt, regulators, gearbox (for airsoft) will be purchased separately. The exterior of the guns would have to be impact resistant and relatively light while the switches and trigger assembly would probably need to be more wear resistant.
