You guys need to study your firearms laws a bit better!
As long as the action has never been used in the assembly of a rifle, it can be used to build a pistol, PERIOD!
A manufacturer can sell an action as part of a rifle, part of a pistol or as a bare action. The legal status of a new action is determined by how it is first assembled. If you first put it together as a rifle, it must always remain a rifle, but, if it is first assembled as a handgun, then it is legally a handgun! I can promise you when Remington ships bare actions to a wholesaler like Brownells, the manifest WON'T list them as rifles, it will list them as actions!
Furthermore, it is perfectly legal (under federal law) for a person, with no federal firearms license of any kind, to buy a new bare action and assemble it as either a handgun or a rifle. No manufacturer's license is needed. It is also perfectly legal (under federal law) for a person, with no firearms manufacturer's license of any kind, to build a rifle or handgun in his garage, out of raw materials, as long as that firearm is built to legal standards (barrel length etc) and is not built for resale.

These are facts, not "I think" or "I heard" or "my dealer said". This information is out there, it just requires a little research, and, forget about calling your local FFL or even you local BATF agent, these folks typically don't know the law. If you want the correct answer to technical firearms questions, call or write the Technical Branch of the BATF, that's what they do. They will research the question and send you the answer in writing, including reference to the specific laws that apply.
Still don't believe me???
Read this and pay specific attention to the 4th paragraph of the BATF letter.

For those too lazy to click the link, it says:
[ QUOTE ]
If an individual were to obtain a rifle type receiver that had not previously been utilized in the assembly of a rifle, a handgun could be made and not be subject to the provisions of the NFA. Verification must be obtained from the manufacturer of the receiver to establish its authenticity.
