With the AWB gone (hopefully for good) are AR style pistols legal again?
If so, what is the way to purchase a 9mm AR style pistol.
And what if after I acquire that pistol, I put a stock on it?
What are the legal hoops?
Thanks

You can purchase an AR pistol from Olympic Arms, not sure on the 9mm, nothing was listed on their website.  If you get a pistol you can NOT put a stock on it without registering it as an SBR (short barreled rifle).  If it has a stock the barrel must be >16 inches (NFA of 1934).  If you want a short barrel with a stock you would be ahead doing that from the start and registering it.  Olympic's pistol does not have a buffer tube, so you can not attach a stock, and other pistols have a very short buffer tube and do not have the provision for a stock.

when you find a 9mm or .45 acp AR pistol, let me know

i havent heard anyone sell pistol caliber ARs, just 5.56

I contacted OA about one of there pistol uppers in 9mm and they said they have plans to release one maybe as soon as a couple of months.

9mmar15.com has SBR uppers that can be used for pistols.
You could buy a OA .45 upper and have it cut to the correct length

Sorry not completely clear the 9mm upper I was talking about will have OA's recoill system which eliminates the reciever extension.    It'll be something to look out for.

9mmar15.com has pistol length uppers. All you need to do is go to someone like model 1 or something and buy a pistol buffer assembly. Just don't put a stock on it or you have an unregistered NFA--big no go.
if you want a stock and a short barrel register the lower reciever as an SBR which is $200 tax and about an 8 month wait from what I read
