hey /k/ is it illegal to make new open bolt guns in the us?

>>31558659
its not explicitly banned but you would need atf approval to build and sell
if you were going to make a one off singleshot or somethingyou could

REEEEEEEEE

>>31558659
Generally, yes, as open-bolt automatics are regarded as Readily Convertible (which isn't untrue).

You could make a gun that only accepts one cartridge in the breech, unable to take a magazine, but it'd suck.

>>31558695
Slavshit gets around though.

>>31559111
im talking about making a open bolt semi

>>31559138
The BATFE doesn't care, they consider it "readily convertible" to a machine gun.

>>31559138
no go
easily convertible according to the ATF

>>31559138
Open-bolt semi-automatics are considered readily convertible to full-auto (because they are, converting an old MAC M10 pistol to full-auto requires no real special tools or knowledge, just grind down the correct part of the sear for 15 minutes and the sear will only interrupt fire when you release the trigger, a machinegun), thus all open-bolt semi-autos made after 1982 (when the ATF made this ruling), are legally Machineguns.

Pre-82 open-bolt semi-autos are grandfathered/exempt, unless you convert them to full-auto, whereupon they are machineguns.

The only way to get an open-bolt semi-auto these days is buying an old one, and they have collector's value. A grandfathered KG9 can go for as much as $4000 dollars, at which point it makes infinitely more sense to buy a registered Sten subgun, which does all the same things but better, and can shoot full-auto.

The cheapest exempt open-bolt semis are probably the old .22LR plinker rifles, but they all only have 5rd mags and aren't very well made at all times.

Has to be single shot, no ejector, no extractor no magazine slot etc. I have an email skmwhere where they specified

>>31558659
There's no specific ruling that states that open-bolt semi-autos are banned, but open-bolt semi-autos meet the definition of 'machine gun' because they are 'readily restorable to shoot fully automatic'. So they kinda are banned.

>>31559257
The 1982 ruling only affects the KG-9.

>>31558659
Yes/no

You can make an openbolt single shot


But you cannot make an open bolt that has a magazine / semi auto.

>>31559485
Ah no. What is M10?
Daily double, ding ding ding, what is M9?

>>31559512
Ok, fine, there were a bunch of other guns like the Sten and other shit.

>>31559235
Is it though?

I've got an old savage 6a .22 rifle.

They fire from an open bolt and are know to go full auto if they get dirty enough.

Technically no. Effectively yes.

For background:

The ATF issued various letters to various companies from 1968 through to 1982 declaring their products to be machine guns. "Machine gun" was originally defined in the National Firearms Act of 1934 as any firearm capable of discharging more than one round with a single actuation of the trigger mechanism. The Gun Control Act of 1968 in part amended the original NFA of '34, redefining "machine gun" as as any firearm capable of discharging more than one round with a single actuation of the trigger mechanism *OR ANY FIREARM READILY CONVERTIBLE TO AUTOMATIC FIRE*. The ATF has not, in the last 48 years, put forth an official definition (or any statement at all) as to what constitutes "readily convertible". It's all done off the cuff. The first reclassification as a machine gun that I can think of off of the top of my head was a small batch of semi-auto Franchi LF-57's brought in by Interarms(almost positive) in the late 60's or early 70's. They had a very small bent sheet steel disconnector that prevented full auto fire, but it could be removed in less than a minute with a pair of heavy pliers and some tugging. The entire batch was required to be registered, so the importer just chopped the barrels down to mil-spec length and sold them as transferables. Another full-on reclassification was the Spitfire in the 1970's(?). What muddies the waters are the reclassifications where the ATF simply ordered the manufacture to end production, but took no further action.

Amongst these are the various Ingram-type pistols and carbines, as well as the Interdynamics KG-9 and one other carbine similar to the Spitfire that I can't recall the name of. Most manufactures had seen the writing on the wall by the late 70's and simply ended production before the ATF got around to banning production or declaring their existing stock to be contraband. R.P.B. was not one of these. They were pretty edgy and kind of the black sheep of the firearms world at the time, doing things like selling "replacement parts kits" for suppressors that just so happened to include every single part of the suppressor, including the tube. (This is what got wipes effectively banned). R.P.B. continued manufacturing their guns until 1982 when the final anti open bolt letter got mailed to their office/factory/warehouse.

To directly answer your question: The opinion letters only affected whatever specific firearm(s) they addressed. There has never been an explicit, comprehensive ban of open bolt semi-automatics. BUT there are only so many ways you can skin a cat. No one has yet come up with a design that wouldn't be declared as readily convertible.

click clack gun, they don't fire from an open bolt, the bolt just stays open until you reset the trigger.

my springfield 87A (same gun), has slamfired 5 round bursts before though.

>>31559485
No, it affects all semi-auto open-bolt weapons, Interdynamics just had a short period (sometime after the ruling, actually) of making the open-bolt KG9 pistols before the ATF came and said "You gotta stop that, we ruled those are readily convertible, change your design." resulting in the KG99

There's a bunch of open-bolt MAC variants which are grandfathered, none are made after 1982.

I never said the ATF was clever or virtuous, merely that they're mostly correct in that open-bolt automatics are very easy to convert.

>>31560616
Yes, the sear from an open-bolt semi-auto is usually extremely similar to one for a full-auto.

On the old MAC10 pistols and variants, it's pretty much just a stem which engages the bolt after each shot, stopping the bolt from cycling like a machinegun.

Before the closing of the registry in 1986, it wasn't uncommon for people to buy a MAC10 pistol, file a form to convert it, then when they got the paperwork, convert it for pretty much free at home, just spending a bit of time grinding that stem away with a tool in their garage.
(this, and the fact that you could often get package deals when a specialist outfitter converted your Colt AR to select-fire professionally, throwing in a MAC10 build for you at a low price, is why there are so many transferable full auto MACs).

A particular illegal case comes to mind, where a Cobray M11/9 pistol which had been illegally converted, was used by some white nationalists to murder a liberal reporter/writer named Alan Berg (inb4 /pol/), then there was probably the odd Jamal and Tuco who did their own conversions, as these guns were actually rather cheap, and converting them was trivial (the guns also look badass)

Crimes with automatic weapons in general was never very common at any rate though, and media from or about the 80's probably gives a false impression of how common this was, the KG9 was the only open-bolt TEC9 variant, and was sold for a very brief time, in very small numbers, yet full-auto ones featured so frequently in Miami Vice (and other shows) you'd think all the variants were that easy to convert (not so). Granted, it wasn't a show rooted in realism and it was very much about style.

>>31560860
Your right! I had to go check its been so long since I fired it. My bad.
Guess it's time to take the old girl to the range!

>>31559257
>Pre-82 open-bolt semi-autos are grandfathered/exempt
Whats to stop me from making a mac and stamping '1978' on it?

>>31560835
Those LF-57's were brought in by MARS equipment co. (same importer of the original CETME sporter), not Interarms.

>>31561839
I think Interdynamic USA did import some MP-9 SMGs as pre-dealer samples.

>>31562331
rip doggo

>>31562331
It had to be registered prior to the date

>>31562420
Yeah, as actual machineguns.

>>31562331
They'll frag your dog, they keep track of those.

Open-bolt weapons, not dogs.
