Building an AR-15 SBR on a Budget: Part 1 – Paperwork

This is chronicling the build of an NFA Regulated firearm in the State of Arizona. This is not intended to be a “How To” guide. Consult all federal, state and local laws before getting involved with any NFA regulated firearm or device.

This will be the first in a long series of posts about building an AR-15 SBR.  The first step is filling out the required paperwork for the BATFE and the Sheriff’s Office.  If one has a Legal Trust, then it is exempt from the Sheriff sign off.

This build will be on the ATF Form 1, the Application to Make and Register a firearm.  Two copies of everything will be needed.  The form 1, along with a fingerprint card and Certification of Compliance (Certification of Citizenship) and a passport size photo.  On top of that a check for $200 for the Tax Stamp.


Before Mailing everything to the ATF, the County Sheriff must sign off on the paperwork.  This can take up to 30 days.

Once sent to the ATF, the current average for processing is about 6 months.  Hopefully this will speed up.

For now my AR-15 SBR is just a lower receiver and a bunch of paperwork.  In time it will become an  Mk18 mod 0 clone.
