Welcome to the SeeMeCNC Community

Here is a 9mm auto printed with the Orion.

Does someone hear the police knocking?

Its not illegal to build a gun in USA if you can own one.

I build guns and that one is kind of terrifying. Your bolt is way too light for 9mm

At the start of the video I thought he made a knockoff of the USFA Zip 22.


You also need to make sure you don't break any of the NFA rules like Short Barreled Rifles or suppressor without having a tax stamp for each item.




With certain exceptions a firearm
may be made by a nonlicensee provided
it is not for sale and the maker
is not prohibited from possessing
firearms. However, a person is prohibited
from assembling a nonsporting
semi-automatic rifle or nonsporting
shotgun from imported parts. In addition,
the making of an NFA firearm
requires a tax payment and approval
by ATF. An application to make a
machinegun will not be approved
unless documentation is submitted
showing that the firearm is being
made for a Federal or State agency.
[18 U.S.C. 922(o) and (r), 26 U.S.C.
5822, 27 CFR 478.39, 479.62 and
479.105]

The bolt weight is 1lb 10 ounces

That's super impressive mate!
I was expecting a replica or prop not an actual one.. Do you have video of it firing? If so I wouldn't upload it unless you'd like unwanted attention :/

He fires it at the end of the video in the op.

I'm not into guns, but that's pretty cool. Will you be posting the .stl files? I have a friend that would love to build one.

needs Tannerite for full effect.

1 pound should be ok - I'd make it as heavy as possible to keep the shock down.

I also wouldn't distribute files for it for the sake of liability. I never did hear the outcome of the ATF rulings on the 3d printed gun thing - I know they had ITAR issues.

AFAIK they threatened Defense Distributed with enough trouble they pulled the files. They still exist on a certain Swedish nautical site however if you really want them.

Really? I must have had my sound down, or looked away when he did that

the laws around 3d printed guns aren't so much about its creation and ability to fire as its ability to be detected. The Liberator didn't have enough metal in it to be detected when passing through modern TSA checkpoints. This weapon definitely has enough metal.

Great design and I'd love to see you post the .stl.

http://en.wikipedia.org/wiki/Undetectable_Firearms_Act passed during the Reagan era, with Congress renewing it every sunset date. It's a ban on the manufacture, possession and transfer of firearms with less than 3.7 oz of metal content, which is the watered down version the NRA was ok with because no existing weapons were affected. The original version would have banned anything with less than 8 oz, which would have made the Glock 17 illegal because of its heavy use of plastic polymer.

I question the authenticity of the Glock comment. Mainly because the gen1 Glock 17 9mm unloaded weights 22ish ounces. Even the new Glock 43 weights 16.9oz unloaded which is the smallest 9mm they've ever made.

Are you adding up total weight? or just metal weight?

Thats total Frame, slide and barrel.

KAS wrote:Thats total Frame, slide and barrel.

Yea, I used to have a G19 and it was the midsize 9mm. Just a "hand scale" estimate would put the slide and barrel at way more mass than the frame when field stripped, at least a third more.

Here is a magazine from 1984 that shows the loaded weight of 27.9oz. https://www.youtube.com/watch?v=hQTahzTEGGw skip to 3:14 at the bottom left.

This is my lightest firearm, and what joeshmoe's video above reminded me of.

http://www.military-today.com/firearms/glock_17.htm
"The only metal parts are barrel, slide and trigger mechanism."

The whole gun is about 22 oz. I'm not finding numbers on the weight of those parts. You may be right, in which case a that wiki is wrong in its claim that 3.7 oz is half the glock 17 metal weight.

Dude.... The aptitude to build that, and you settle for thick leather gloves?

I mean, yeah, that'll probably work in the event of a catastrophic failure, and kudos to you for doing anything at all to minimize the risk of personal injury, but couldn't you go the extra mile and build a vice for the damn thing so you could fire it by pulling on a string? Seriously...

Not only does it make for better video, but also you can flex its muscles in safety, and in the event of some tragic combination of design flaws manifesting themselves as a transition from gun to grenade, we (the people of this great nation, and others) won't have to worry about new laws being put into place that infringe upon our right to arms, privilege to print them, or the privilege to print things at all.

Feel free to ignore all of that, but if you decide to do so, please don't post your shit on youtube, and if you perforate your hand one day, or lose an eyeball, blame it on the acute onset of an extremely localized hail storm, or a bad television.'


Also: Very awesome work on that little bugger. Not sure how I feel about a lack of extractor, but great strides nevertheless.

I had already put 100 rounds through it on a vice.

Latest video. https://youtu.be/REGeDjuADXI

Whatever you do, don't put a stock on there! Pretty sure it's almost into the SBR territory as it is.

Still bustin caps! Was that just the microphone on the camera doing compression or did the gun actually sound a lot different as you fired more rounds?
