This video explains ATF definitions for AR pistols versus rifles, focusing on barrel length and overall gun length. A firearm is classified as a pistol if its barrel is under 16 inches, requiring a brace. If the overall length exceeds 26 inches, a vertical grip may be permissible even on a pistol configuration. Rifles, defined by a barrel over 16 inches, can use stocks and are generally over 26 inches overall, allowing vertical grips.

Quick Summary

The ATF classifies an AR firearm as a pistol if its barrel is under 16 inches, requiring a brace. If the overall gun length exceeds 26 inches, a vertical grip may be permissible. Rifles, with barrels 16 inches or longer, can use stocks and generally allow vertical grips due to their longer overall length.

Frequently Asked Questions

How does the ATF define an AR pistol versus an AR rifle?

The ATF primarily defines an AR pistol by its barrel length being under 16 inches, requiring a brace. An AR rifle has a barrel length of 16 inches or more and can use a stock. This distinction is crucial for legal compliance.

When can I legally attach a vertical grip to my AR pistol?

You can legally attach a vertical grip to an AR pistol if its overall gun length measures over 26 inches. This measurement is taken from the end of the fixed barrel (or pinned/welded muzzle device) to the end of the buffer tube.

What is the key difference between a pistol brace and a rifle stock?

A pistol brace is used on firearms classified as pistols (barrel under 16 inches) to comply with ATF regulations. A rifle stock is used on firearms classified as rifles (barrel 16 inches or longer) and provides a different shoulder interface.

How is the overall gun length measured for ATF regulations?

Overall gun length is measured from the top of the threads of the fixed barrel (or pinned/welded muzzle device) to the end of the buffer tube. If the muzzle device isn't pinned, it's removed, and measurement starts from the top of the threads.
