Summary: written with AI from the case record.
What it's about
He also asks whether the Second and Fourteenth Amendments protect possessing an AR-15-style rifle with a device that lets it fire ten shots with one trigger pull; the petition is pending.
The petition links a federal sentencing dispute about an earlier state conviction with a separate constitutional challenge involving a rifle conversion device.
Question presented
1. Whether, consistent with federal statute mandating the application of the United States Sentencing Guidelines in effect at the time of sentencing, a sentencing court must look to the validity of a state prior at the time of federal sentencing to determine whether the state conviction qualifies as a predicate offense for a recidivist sentencing enhancement under the United States Sentencing Guidelines? 2. Whether the Second and Fourteenth Amendments guarantee the right to possess an AR-15 platform semiautomatic rifle outfitted with a conversion device or a conversion device which allows an AR-15 platform semiautomatic rifle to shoot ten times with a single pull of the trigger?
What happens next
The Court must decide whether to hear the petition. It was distributed for the Court’s Nov. 13, 2026 conference; that does not mean review was granted or guarantee a decision date.
