COLT AR Built As a Rifle and Transformed into a Pistol Legal ?

[TexasAggie2005]

Colt sold complete lowers via Brownells. They were not take offs and would have been received by FFL's as a receiver, even though they shipped with a stock. These specific lowers could be used as pistols with the correct changes (addition of a brace etc). These had LE prefix SN's.

A rifle is forever a rifle, and can not become a pistol, no matter what receiver extension is bolted to it. Brace, no brace, etc. An item is dictated a rifle or a receiver (or a pistol) by the MANUFACTURER not the receiving FFL.

Calling said mfg with the SN will clarify that firearm's disposition as it left the factory.

FWIW, I bought one of those in September 2018, and it had a CR prefix.

This is good advice. It might take a while to grab a hold of someone at Colt on the phone, but they will tell you what the original configuration of the lower was. I've done it.
