This is a firearm. It requires an FFL transfer before you can take possession. Pick it up in person at our store (4755 US-280, Birmingham, AL 35242), or have it shipped to the FFL of your choice anywhere in the country.
A completed ATF Form 4473 and a NICS background check are required at pickup, per federal law. A valid Alabama concealed carry permit (regular or lifetime) can serve as an ATF-recognized alternative to the NICS check.
Buying this listed item directly from us carries no transfer fee. If you'd rather ship in a firearm you bought elsewhere for us to receive and transfer to you, that incoming transfer runs $50. See our FFL Transfers page for the full process.
