Here are pictures from someone who went and made one of the conversion kits for an AR. It is a 3D printed, drop in kit that converts a semiautomatic AR into select fire.

To the ATF: These are not my photos, they have never been in my physical presence, and I don’t even own a dog. I don’t have any weapons that you would consider illegal. I am publishing this strictly for educational purposes. I am advising people to never make one of these, because they are illegal and we are law abiding citizens.

Nice try. BATF will bring their own dog just so they can shoot it in your house.

I believe the green thingy is what the atf called a picture hanger , you could buy them on line a few years back.

That’s not even real anyway. That’s a CG rendering.

I wonder how well that holds up during use?

You can never stop the signal.

@DM: Think outside the box. Just keep a bound book of customers with the names and addresses of every Democrat from city dogcatcher to POTUS, and every reporter from the local fishwrap to the network anchors. Be sure and let them know it’s one of eight copies.

Be Ghislaine, not Epstein. 😉

Good demo kit…could be made pretty easily from steel stock if you had some access to some basic machining equipment

Is Moldless-Cast Plastic (that’s what it really is, “3-D Printing” is an Oxymoron) going to hold up to the Impact and Heat in a Firearm that is spewing Hot Propellant Gas into the area where the Trigger Group is located?

    They 3d print handguns and even full AR lowers.

What’s the durability of 3D printed plastic in a FCG?

I don’t have a government level ammunition budget.
Or a D-3 Print Thing for that matter.
But yes, you can’t stop the signal.
