How You Get This Firearm

Pickup or ship to your FFL

This is an NFA-regulated item. It requires an FFL transfer (and, if not already completed, your ATF tax stamp) 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.

Paperwork at pickup

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.

Transfer fees

Buying this listed item directly from us carries no transfer fee. If you'd rather ship in an NFA item you bought elsewhere for us to receive and transfer to you, that incoming NFA transfer runs $75, in addition to your ATF tax stamp. See our FFL Policy page for the full process.
