Home Made 3d printed guns anyone?

[AlienHobo]

My next challenge: 3d printing an ar lower (legally of course). I'm thinking taking a broken ar lower (or breaking one) and replacing the broken parts with 3d printed parts (is that legal? back to the law books I guess).

If you have any questions or suggestions (or you have a broken AR lower) let me know.

Now, there's an idea. I don't know about 3D printers, but can you take a chunk of metal and 3D print onto and around it, thus embedding the legally required metal for creating a home made gun in CA?

photobucket makes some of these really low quality.

That said, this is neat. I figure it's part of the printing waste material, but I like how one of them almost looks like a paintball marker with that big trigger guard.

It'd be interesting to see how the frame handles the stress of firing, and what you can do to toughen it up. Maybe metal reinforcements somewhere?

Let us know how it handles!

Fosscad. Never heard of it.

I'm not too sure that your claim that the serial number on the slide or fire control unit take's care of the requirement for the 3.7 oz stainless plate embedded in or attached to the frame.

Sig FCU is the serialized part. It is not like Glock or cz where the entire frame is the serialized part

That trigger guard seems like it can be made to look like a forward grip.

I think you can print a gun with a 3D, but I don't think your local police officers will agree with that. Actually, that's quite impressive how using a machine you can create anything you want even guns, fantastic.

You can buy a $500 mini mill or lathe from a harbor freight and make guns. Bruce Gray makes a lot of custom parts the old school way, with a file.

Let us know how the material holds up. This is a great way to reproduce movie props.

What printer did you use? I'm in the market for a new 3d printer that can print a wider array of materials.

Doesn't look to me like you built anything. You took an existing fire control unit and slide and dropped those into what looks like an ND waiting to happen, that you 3D printed.

It seems a couple of people don't understand how the P320 works.

The serialized part is the fire control unit. That metal piece that contains the trigger is the "gun." What the OP 3D printed is considered the grip unit.

If you own the serialized part, you can change out the grip and slide as much as you want. The fire control unit can be dropped into a full size, compact, and sub-compact grip/slide kit.

This is an interesting hobby. But as mentioned, OP did not actually print what is considered a "ghost gun" and therefore does not have to comply with any of the nonsense of oz's of metal, etc. He printed a frame for a p320 fire control unit. Lots of places selling p320 frames without "serial numbers" since they don't need them, as explained above. Wilson combat, Gray guns, even Sig will sell anyone a p320 frame over the internet and send it right to your home! How scary! Good to see the OP putting his ingenuity and creativity to work.

He's just adding parts to his legally-owned gun. Don't understand how some people can't comprehend that.

Until you print with nylon, I would suggest firing the ABS plastic from a rest just in case.
