3D Printers are awesome

It's functionally identical to an actual Colt-style Auto Sear; So with a full-auto FCG, you'll have safe-semi-auto capability. It's worth noting that Drop-in Auto Sears don't allow for burst-capable fire control groups (since there's no space for a ratchet-tooth mechanism).

Yes they do. The ratchet tooth is mounted on the hammer. Not the sear.

Is this a fraud?

Found on here: grabcad com/library/drop-in-auto-sear

But who was phone?

I stand corrected! I genuinely thought the ratchet attached to the sear. Did a search after your comment, and you're 100% correct.

The thing you lose is the sear not tilting back when you need to closed the receiver.

ATF has better things to do with their time.

That's an AR-15 drop in auto sear

Looks like I need to get a cheap 3d printer.

Just to make some keychains, of course.

Very worth it.

Too bad Drumph is telling the ATF to reinterpret what makes a gun a machinegun, to include accessories (FCG) that make the gun capable of functioning like an automatic weapon.

FCG+AR-15= constructive possession anyway. The only benefit of this is that 99% of LEO have no clue what they're looking at and you don't have to permanently modify the lower with the sear hole.

FOSSCAD has it, along with 3-pin lowers

if you don't own any dogs and don't mind your house burning down i'd recommend the lower - i don't trust a printed DIAS

What you mean is that it does not disengage, which makes its use in a select-fire weapon a mystery or even

Nice try atf

Make no mistake, drop in auto sears work, they just won't sit vertical while you close those receivers.

So how durable is that?

How is it not automatic only if the sear won't disengage, the A1 sear assembly interfaces with the selector, the DIAS does not

Ahahaha! Me too like to make non-registered weapon parts in my garage!

Could you please share your address so we can exchange tricks?

>non-registered
Commerce Clause doesn't apply to items that are never transferred/leave the state

doesn't matter. The reason a factory sear interfaces with the selector is just because it makes it easier to assemble it, instead of your bolt carrier running against the sear. No other function. A drop in is functionally the same as if the factory sear always swung freely like in an AK.

>3D Printers are awesome

No, they make useless plastic crap.

>fuckthepolice

Not a fan of authority but we do and always will need police and you have a stupid attitude.

Boot licker detected.

intra-state items affect the overall market, and thus fall under inter-state commerce.

>he hasn't heard of lost wax casting
>or printed at lowers
P L E B

Not if the item is never sold (transferred), it is the exact same reason an %80 lower completed by you requires no serial

>No, they make useless plastic crap.
this
get proper tools, you retard

You can transfer 80%s though. You don't need to serialise because homebuilders are not FFLs and have no legal requirement to serailise.

That would only work in "semiautomatic" mode if the disconnector somehow catches the hammer before the hammer clears the sear, which would imply the angle of travel for the hammer is different in automatic mode

Again: I put 750 rounds through the DIAS, and it ate them like a champ. No stress or failure points anywhere. I'm going to be doing another stress test in a week or so, after leaving the part in the sun to see if UV exposure will affect the material. I suspect it won't, and the component will run just fine.

No. The FA FCG is different from the SA FCG. The sear works because the hammer has an extra catch on it that can only be engaged by an auto sear if the safety selector is set to FA.

Plastics and Composites are versatile, useful materials as long as you understand their limitations and utilize the materials in ways that they can withstand.

"Retard."

The ATF already interprets full auto FCG as machineguns, that's not new.

You have a fundamental misunderstanding of 80% firearms. Non-licensed manufacturers are only required to serialize their firearms if they are manufactured with the intent to transfer to another person. Serials are intended to be used for tracing a firearm; if it is not intended to be transferred, there is no requirement for a serial number.

This also means a non-serialized 80% may be transferred at a later date. It has nothing to do with interstate commerce.

>he Supreme Court provided one of the earliest and most foundational expositions on the Commerce Clause in Gibbons v. Ogden, 22 U.S. 1 (1824). There, the Court found that intrastate activity could be regulated under the Commerce Clause where it was part of a larger interstate commercial scheme. Later, in 1905, the Court used the Commerce Clause to halt price fixing in the Chicago meat industry, when it ruled that Congress had authority to regulate the local meat market under the Sherman Anti-Trust Act. In Swift and Company v. United States, it found that business done even at a purely local level could become part of a continuous “current” of commerce that involved the interstate movement of goods and services.

>Non-licensed manufacturers are only required to serialize their firearms if they are manufactured with the intent to transfer to another person
There is NO federal requirement for non-FFLs to serialise, even if transfering the firearm.

>Interstate commerce claus
Fuuuuuck that. God damned bullshit be the Wickard v. Fillburn case!

11. Do I need a Federal firearms license to make a firearm for my own personal use,
provided it is not being made for resale?
Firearms may be lawfully made by persons who do not hold a manufacturer’s license under the
GCA provided they are not for sale or distribution and the maker is not prohibited from receiving
or possessing firearms

atf.gov/firearms/qa/does-individual-need-license-make-firearm-personal-use

If you are manufacturing it with the intent to transfer, you are engaging in the business of manufacturing and selling firearms and must be licensed. Licensees are required to serialize firearms.

You are correct that there is no federal requirement for nonlicensees to serialize their firearms, but you are incorrect in suggesting that they may manufacture firearms with the intent to transfer without serializing. Intent to transfer means they must be licensed, and thus serialized. A nonlicensee is never allowed to manufacture a firearm with the intent to transfer, serialized or otherwise.

> but you are incorrect in suggesting that they may manufacture firearms with the intent to transfer without serializing
Never said that. I said you may transfer without serialising. That is distinct from manufacturing with intent to transfer.

Your sear makes contact with your BCG in all three selector positions, its under more stress than a conventional sear!

>that's not new.
No it doesn't nigger. You can buy FCG spares for your rifle now problem. It's only constructive possession (currently) with an AR-15 lower and an auto sear.

Drumph's faggotry would make the FCG a defacto MG like possession of a LL or DIAS would be.

Fuck Drumph desu senpai.

What is all this? new poster and curious

You misspelled Drumpf, also pre-81 DIAS aren't considered MGs without an AR-15 lower

Now I have a actual use for my 3D printer! Thanks!

>Regardless of the date of manufacture of a drop in auto sear (i.e., before or after November 1, 1981) the possession or transfer of an unregistered drop in auto sear (a machinegun as defined) is prohibited by the National Firearms Act (NFA), 26 U.S.C. § 5861, and the Gun Control Act, 18
U.S.C. § 922(o).
They are machine guns. They had been exempted from the taxes on making and transfer.

Lightning link. Makes an AR-15 with an SP1 style bolt carrier go full auto only.
>pre-81 DIAS
Nice meme. The ATF vanned the guy selling those out of SGN a few years back. There's not such thing as grandfathered DIASs in the same way that a pre-86 MG you've always had before the ruling is still illegal..

Don't forget that clever cunts can also use 3D printers to make lost wax style castings. You can just melt some aluminum or brass down with a propane torch and produce a casting. You'd still need to do a little finishing work to remove the rough edges, but you get a metal part.

>FCGs are machine guns
No they aren't. You can buy FA FCGs with no hassle right now. Things get tricky if you own a gun that can use that FCG though.

Hi, Agent Bob. Are you mad that you're working on a Sunday?

We're discussing safety sears, they prevent light primer strikes and/or out-of-battery fire. They also act as a wedge to eliminate slack between your upper and lower receiver :3

Seriously though guys. Why isn't this a thing?

yeah and 99% of people who own a 3d printer own an SLA printer, which produces parts that are much less tolerant to stress

I want a 3D printer but I'm probably not going to do gun stuff with it. The only thing I'd try is to make a scope body to transfer the guts from this toy NVG set into so I can have a cheap NV solution for my WASR and shitpost IRL at night shoots.

FYI the dimensions seem to be a bit off. Slightly too long to work as intended.

Oh that is a nice can opener.

is it to hard to mold it and copy it with some modern Zink or Alu?

Lost casting is possible yes, but casting is a bitch to do regardless of how you form the mold. Hope you got the space and accommodating neighbors.
I'm just gonna use mine to make stuff like bistable latching hinges for projects. Just general stuff that would be a cunt to make by hand.

Although the temptation to make a WarFairy lower is strong.

It's illegal to produce DIAS without a Class III License since 1986.

Cast metal is also typically very brittle, which is not a characteristic you want in actuating or impact-absorbing parts.

You wouldn't want to mold it. If you're looking to produce this out of metal, you'd ideally want to mill them. The operations necessary aren't complex - though if you plan to produce many of them, you'd ideally want to create yourself some mill jigs first, just to make your life easier.

You'll want the sear paddle to be rigid, but the sear body to be a little flexible, with a very slightly undersized pin hole (so when you drive the roll pin through, it won't rotate as the paddle is actuated [to prevent the hole from egging out]).

Print material and print orientation will help mitigate stress-related failures on lower quality printers.

Because it's illegal to produce an entire drop-in full-auto sear unit. It doesn't matter what the trigger and hammer are capable of doing, but the sear is the problem. There won't be a professionally designed / developed self-contained full-auto combined trigger and sear assembly because it doesn't make sense to make one, from a manufacturing and maintenance perspective.

>because it doesn't make sense to make one, from a manufacturing and maintenance perspective.
Well I guess you should tell H&K. I'm sure their engineers will be interested in your expert opinion.

Laser melting plastic powder. Was expecting run of the mill FDM printer. Can ya print something from FOSSCAD?

Are binary trigger packs for MP5s ever going to drop down to reasonable levels? Are they 3d printable? I can't justify spending $500 on one

AR trigger packs cost about the same, and the MP5 is a special snowflake Kraut gun. So no, they won't get much cheaper.
