AR "Pistol" vs AR "Rifle" - ATF Rules Explained and When You can Use a Vertical Grip
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.
