Is there an experienced Person out there who can tell me about the procedures you need to do in order to create a receiver? I am unsure of what sort of transfer stuff you would have to do. Also Whom would i ask to determine what sort of features i could have in the rifle, I find the legal definitions confusing. im thinking of trying to implament such features as getting around the magizine cap for semi rifles by using a bolt catch with a manual release in the form of a button or something. basically a small quick switch to mantain the rate of fire of a semi with the large magazine of a bolt action. i havent seen anything telling me i cant do this. If there are people out there who could help me with this it would rock my socks.
