Amazon.com has AR accessories

Basically any length.. I've seen them down to 5 inches or so.. And you can put a 16" or longer barrel on a pistol as well.. It's just if it has a barrel length of less than 16" (16.1" to be safe), it must never have been sold as a rifle.. If you put a butt stock on it, it better have a barrel longer than 16 inches or pay the tax and do the paper work for a SBR - which I would really love, but don't want to deal with the NFA rules and stuff..

So I keep my AR Rifles, AR Rifles, and my AR Pistol an AR Pistol.. Life is good..
