Is a firearm that fires from an open bolt OK to posses if it is only a
single shot?

Any weapon that fires a single round with a single pull of the trigger
is ok.

Open or closed bolt.

The ATF may get shitty about it though if you have a magazine. Open
bolt firing is typical of full auto weapons of older styles and
conversion to full auto is....easy.. at that point....

They really dont like that very much

The one problem with open bolt firing single shot arms..is the slide
tends to move the weapon away from the aiming point as it slams forwards
and fires. On a full auto weapon..thats not a big concern. On a single
shot..its a serious concern.

IANAL, but if by "OK to possess" you mean legal-wise, I'd say "almost
certainly yes". There's a basic doctrine in American law that pretty
much boils down to "If there isn't a law on the books that specifically
prohibits <insert whatever item/act is being discussed here>, then
making/possessing/doing it is legal". So far as I know, there's no law
on the books prohibiting such a beast as shown in the vid. (although
selling it is almost certainly going to be a different story than simply
making/possessing it)

What do you mean by "OK to posses"? Legal? What would firing from an
open bolt have to do with it?

Or a submachine gun.

I'm not exactly sure what the point is... Is it to intentionally make
a LESS accurate single shot, or to shoot slightly faster than a normal
single shot but much slower than a semi-auto? Or is it just to say he
did it?

There have been a number of such guns sold in the past, mostly cheap .
22s. They're legal to possess. There's no manufacturer in the US of
such right now. Open bolt firing being a characteristic of machine
guns, the applicable phrase in the NFA of 1934 is "readily
convertible". ATF gets to define this, I've read of 8-10 hours in an
equipped machine shop being the definition at one point, it can and
will change. A whole lot of wiggle room there. So if a magazine
housing or other gadget could be attached somehow and the thing could
fire more than one shot with one trigger pull, it's then a machinegun
and if it's an easy enough conversion, the ATF can sieze the
unmodified guns as being "readily convertible". So open bolt=bad
design, at least in the US for civilian shooters, particularly if it
resembles a military firearm of some sort or is derived from a full-
auto parts kit. They probably aren't going to do a mass round-up of
old open-bolt single-shot .22s, unless somebody adds a magazine.

I was just wondering. You have pretty much summed it up for me.
Thanks,

The ability to say he did it.

And its "cool" to some.

Frankly..having to engineer something that actually stays together until
opened up is "cooler"..but then...Im a machinist

AFAIK, there are no laws prohibiting an open bolt firearm per se. If
anyone has a citation to the contrary I am sure they will gently
correct me. ;>)

There have been several open bolt 22s sold in the US.

Winchester cornered the semi auto singleshot market, such as it is,
with the Winchester 55, which operated like the pistol in the video.

Marlin made an open bolt semi with a magazine, the Model 50.

BSA sold a few (very few) Ralocks, which were open bolt and had a tube
magazine similar to a Browning SA22.

Gevarm had the E1, which was open bolt and had a magazine. It did away
with such luxuries as an ejector and extractor.

Voere made some 2005s, which were open bolt semis with a magazine.
There are rumors that ATF prohibited them, but I have never been able
to find a definitive ruling as to their legality to possess or if they
were barred from importation. They would be relatively easy to convert
to full auto, but then so would most semi auto 22s.

Open bolt is a plus on machine guns, but causes inaccuracy and heavy
trigger pulls, so has never been popular.

According to Wikipedia entry for "open bolt":

and here's the foot note:

http://www.atf.gov/firearms/nfa/nfa_handbook/nfa_handbook-rev0409.pdf

Unhappily that link is dead, but this one leads to a current version of the
NFA Handbook:

http://www.atf.gov/publications/download/p/atf-p-5320-8/atf-p-5320-8.pdf

I did a search on "open bolt". On page 141 and following, there are
discussions of a number of weapons (including the KG-9 pistol, the SM10 and
SM11A1 pistols, SAC carbines and the YAC STEN MK II) which were all
classified as machine guns subject to NFA regulation in part because they
fire from an open bolt.

The key factor in each case that the open bolt combined with certain other
(easily modified) parts (like disconnectors and trip levers) allows the gun
to be easily converted to fully automatic weapons.

In my *very* quick perusal, I didn't see anything of a blanket statement
that all open bolt weapons are subject to NFA rules.

HTH..

Thanks. It's my guess that it would have to be semi-auto and open bolt
to run afoul.

I did some searching on the ATF website for "open bolt" and found the
same thing; a few guns *specifically* named as NFA weapons because
they were open bolt, but no evidence of an across the board ban.
Still, it would certainly discourage a manufacturer from making one
now.

The best reason not to make an open bolt semi is that the heavy
trigger pull inherent in the design and the slamming bolt make it
inaccurate. The sole advantage in semiauto use is that you can make an
open bolt really inexpensively, but not so much so that it's worth
fooling with.

I have an open bolt semi-auto 12 ga.
It is an SWD Terminator 12.
Being it is a single shot, the ATF is OK with it.
