| I have been thinking about machining a lower reciever from scratch, but in four pieces. It woiuld consist of two side plate, a buffer tube attachment lug, and pistol grip attachment lug. The two side plates would be attached with a couple of alignment pins to locate them and two counter sunk bolts. Machining the parts this way would allow me to more easily machine the insides of the reciver. I am planning on starting to create the CAD parts within the next week or two if i get time. If this works out, i am thinking this would be a good winter project. There is no real practical reason why i want to do this besides seeing if i can. Any thoughts? |

Quoted:
Been done before, was declared illegal by ATF if I recall.. How could it be declared illegal? Correct me if I am wrong but it sounds as if he was going something similar to a 0% forging, just in four pieces that screw together. Last I checked it wasn't illegal to build something yourself, look at all the 3D printing going on right now. You just can't do it with the intention of selling it. He already said there is no practial reason for doing it and I can't think of any either. Personally I would think it might be kinda dangerous. But when has that ever stopped us javascript:insertText('  ');

What you propose is NOT illegal.....and I'd love to see you do it......I like the idea......the problem with the one that is being referred to was it was being produced commercially and it exceeded what the BATF considered a non firearm......as long as you don't include the hole for the auto sear unless you have the proper license...then you are good to go. and if you want to make it for sale........with out an FFL....just submit a sample to BATF Tech branch and get an approval letter

| Thanks for the input. I have no intentions of selling the components or CAD files. This would be for my own use. The main reason i want to do this is to have a project to keep me busy. I've assembled a few AR's and built one from an 80% reciever. I figured the next step would be to try to build the reciever from scratch. With the mill that i have i think i have a better shot of this working then trying to machine the entire reciever from one block. |

Those are some great pictures, thanks! I am going to try to avoid having to use my friends CNC mill, so i will be using primarily a mill with just a DRO. That will change how i machine some of the features.
I figured this had been tried at some point, but have not seen any examples before. Thanks again for sharing the pictures. |
