Our forefathers owned cannon and Gatling guns with the governments blessing.

Plain citizens may still own a new-made Gatling without any greater government involvement than that required for buying a rifle or shotgun.
Colt’s has reintroduced their M1877 “Bulldog” gun, chambered in 45-70. Pricey: upwards of $50,000.00. Likely cheaper than an original.
Federal firearms regulatory agencies have permitted transfer of Gatling guns all along without special fees or background investigation. Hand-powered only; no Mini-guns except in compliance with rules and taxes specified for machine guns.
