If you used this carbine conversion kit on a 1911 pistol manufactured in the 1930s, could you thread the barrel and put a suppressor on it?

I say you can, since the receiver of the firearm is the lower part of the 1911 pistol (which is pre-ban) and the upper unit and barrel are simply accessories.  You don't have to go through an FFL to get them, so shouldn't that legally allow you to thread and suppress (after paying your $200 NFA tax for the suppressor) this carbine?

Thoughts/comments?

I'm not an expert, but here's my stab at this.

First, you're not only dealing with the NFA, you're dealing with the '94 AW ban.

Lesse.  You make a pistol into a rifle.  Okay; you're good so far.

You want to thread the barrel.  No good; a rifle can only have one evil feature.  You've got yours already with the "protruding pistol grip."  And, since the ATF considers a silencer to also be a flash suppressor, you're technically threading it for a flash suppressor.  No good.  (This is why no postban barrels are threaded on rifles.)

Using "lugs" won't work, either.  You're still sticking on what the ATF considers to be a flash suppressor.

Also, the date isn't the end-all and be-all of the AW ban.  The clincher is that the firearm had to be an assault weapon [i]before[/i] the ban!  In other words, if you had an AR-15 lower that was manufactured in the 1970's but was never made into a complete weapon, it's as good as a post-ban.

Nice idea, though...

[b]However[/b], if you were to forget the rifle idea, it may work.  I don't know a standard 1911's weight.  But, if you stick on a threaded barrel, there's your one allowable evil feature.  Flash suppressors aren't "evil features" on pistols, so you should be just fine!  The only thing that could screw you is the 50 oz weight limit.  Just keep the UNLOADED pistol under or at 50 oz, and you're fine.  

NFA and legal people...  Are my statements sound?

EDITED to add the last paragraph.

Mike, I think you've hit it squarely on the head.

Right now, that pistol, although manufactured in the 1930's is still just a pistol.  When you add the stock it becomes a rifle - and not before.  Therefore, when you add the stock and make it a SBR, youare technically creating a new rifle (the rifle didn't exist prior to that point).  As its now after 1994, that rifle has to comply with the '94 AWB, even though its an NFA weapon.  You'd have a detachable mag, and a pistol grip - you can't have any other assault features, and a supressor would certainly be one.  No dice.

i dont think hes talking about just a shoulder stocked 45 i thikn he means one of those carbine kits with the 16 inch barrel. as far as adding a supproser on a carbine kit if u had teh kit pre 94 with a threaded barrel nope cant do it. sorry it would be a post ban AW but u can add a threaded barrel to a regualr 1911

One question: The 50 oz. limit, how does this effect the race guns, which when loaded weigh more?

The law looks at the weight of the gun [b]unloaded[/b].  No worries!
