Adds a federal definition for a “less-than-lethal projectile device” and creates a procedure for asking the Attorney General to decide whether a particular device meets that definition. The Attorney General must make a determination within 90 days after receiving a device for review.

The change is limited to defining the term and establishing an adjudication timeline; it does not itself create new criminal penalties, spending, or purchasing rules, but it creates a formal federal process that could affect manufacturers, sellers, and agencies that use these devices.
