Muskets from the American Revolutionary era are largely exempt from federal and most state gun regulations in the U.S. [1].

This exemption creates a significant legal gap where historical weapons are not subject to the same restrictions as modern firearms. Because these weapons are classified as "curios and relics," they often fall outside the statutory definition of a firearm [1], [4].

Under federal law and the majority of state statutes, these antique weapons are not subject to standard gun-control restrictions [1], [2]. This legal status extends even to individuals who are convicted felons [4]. While the exemption is broad, some variations exist in how different states apply these rules [2].

Technical specifications of these weapons illustrate their distance from modern technology. A typical Brown Bess flintlock musket features a .75 caliber [3] and utilizes 165 grains of black powder [3]. These weapons, such as those dating from 1776 [1], [4], produce a muzzle velocity of around 1,000 feet per second [1].

Because they are not defined as firearms under many statutes, the acquisition and possession of these 18th-century tools remain largely unregulated [4]. This allows collectors and historians to maintain pieces of the Revolutionary era without the licensing or background checks required for contemporary weapons.

“Antique firearms are classified as “curios and relics” and are not defined as firearms under many statutes.”

The legal distinction between 'firearms' and 'curios and relics' reflects a legislative priority to preserve historical artifacts over the comprehensive regulation of all projectile weapons. By exempting 18th-century muskets, the U.S. legal system acknowledges that the low rate of fire and obsolete technology of flintlocks do not pose the same systemic public safety risks as modern semi-automatic weapons.
