What's the laws on this? It has a 16.25" barrel.
thanks |

Thought the commercial ones were only made with a 18.25" barrel, no regs. The originals were 14", I think they're classified as AOW's.
Between the length and goofy trigger guard I found them kinda unwieldy compared to an original M6, but I still wouldn't mind having one for the right price. |
Same as any other gun. I tried to like mine but I really couldn't see any real use for it that wouldn't be better served by my Marlin Papoose. It was awkward to carry and shoot and I never was any good with wingshooting .410 so I sold it; kind of wish I hadn't as mine was apparently a factory camouflaged model which is rare.
ETA- how are you measuring it? Are you measuring just the barrel in front of the block or are you sticking a rod down the barrel and measuring it? Measure the entire barrel and it should be 18.5" which is legal for a shotgun. |

I got one as a gift. now I got to start a ammo fort of 410 ... The .22lr is up the mom's cellar rafters Quoted:

It really should have a 16" barrel. .410, being less than .500, shouldn't need to meet the definition of shotgun to avoid being an SBS.
Works for the Taurus Judge, after all. The only reason the Judge had to be rifled is the prohibition on smoothbore pistols. To my knowledge rifles have no such requirement. |

Not allowed to have a smooth bore under 18" to the best of my knowledge. There were some smooth bore .22 long guns early last century. AFAIK, they are a no-go. It could be that they were grandfathered in like the short lever gun (forget the model) and the Stevens tip up single shot .22 with the wire stock. I've had a couple of the M6 guns. Never measured the barrel but I'm betting they are 18"+ I wish I'd kept them, now. Appears they are somewhat of a collector item. I bought and sold them for about 150. Edited for error. |

I have three of them. They're great. CZ made them, Springfield was the importer. You can remove the trigger guard so you can fold it all the way, but the barrel still sticks out further than the butt stock.
The original was made by Ithaca, and packed in AirForce ejection seats. They're rare. |

What I said was: It should have a 16" barrel, not an 18". Smooth bore 16" barrel with <.500" bore should be fine... I'm going off memory of the CFR, but I'm pretty sure that is an acceptable non-NFA combo. ETA: Digging into it, it looks like 18 USC SS 921 (a) 5 messes this up. It may have to have rifling to be legal at less than 18" but more than 16". Would straight-rifling work? That is a thing.

Pretty sure there's no bore or caliber distinction. The .5" bore size differentiates a DD. An exception is granted for guns over .5" if they have a "sporting purpose". From wiki: The M6 design and model number come from the M6 Aircrew Survival Weapon, issued to U.S. Air Force aircrew from the late 1950s until the early 1970s. The commercial model is nearly identical to the USAF version, though there are a couple of minor cosmetic differences. There is a removable trigger guard. The greatest change is that the commercial model has a barrel length of 18.25 inches (46.4 cm) instead of the 14 inches (36 cm) barrel length of the USAF version. Athens Arms produced a 14" barreled version that qualified as "Any Other Weapon" (AOW) under the NFA exemption for the Marble Game Getter: combination of rifled and smooth bore barrels between 12 and 18 inches |

I'm trying to find a way to make it shorter. I thought the no-smoothbore rule only applied to pistols. Re-reading 921 it looks like it indeed must be rifled if under 18" of barrel. Now I'm wondering if straight-rifling counts.

It had a jet powered projectile but F troop still classified it as a firearm so it had to be rifled. The "rifling" they put in the bore was not much more than a scratch. I don't think the ATF specifies how deep the rifling has to be. It may have to be spiraled, though. I'll bet that "impart spin to the projectile" is some part of the definition of rifling. You could get one of the .22lr/.22 Hornet ones and shorten it to 16". IMHO, the rifle round would be more useful anyway. |

They are a great gun, if someone else owns it. Nearly useless if you own it. BTDT. Yep. They would be pretty far down my list of desirable guns if I were a shot down pilot. A suppressed MK2 or suppressed G17. Maybe a SBR, suppressed AR with a .22 conversion? If you're in indian country in the ME, you're pretty much fooked, anyway. Anything that you can blow your brains out with would suit. ![]() |
