US12638259 - Multiple caliber sound suppressor with adapter for use with muzzle accessory
The patent describes a versatile sound suppressor system that allows for the attachment of a suppressor to various firearms with different calibers by using an adapter and interchangeable forward walls. Each forward wall is designed to align with the firearm’s muzzle and features a unique bore that accommodates the specific caliber, enhancing the suppressor’s functionality across multiple firearms.
Claim 1
1 . A system for installing a sound suppressor on one of a plurality of firearms, each firearm having a muzzle accessory mounted thereto and each firearm being of a different projectile caliber, the system comprising: an adapter configured to attach to the muzzle accessory; and a sound suppressor configured to attach to the adapter, the sound suppressor comprising: an outer housing having a cylindrical interior and an open forward end; and a plurality of forward walls removably securable to the forward end of the housing and interchangeable with one another, each of the forward walls defining a through bore positioned along the forward wall to align with a central axis of each of the muzzles of the firearms when the forward wall is secured to the housing, each through bore conforming to the caliber of one of the firearms; wherein each forward wall defines a rearward surface configured to face an interior of the outer housing, each rearward surface defining a truncated conical deflector portion annularly surrounding the respective through bore of the respective forward wall and extending radially forward from a perimeter of the the respective through bore, each rearward surface further defining an annular concave trough encircling the respective truncated conical deflector portion and through bore of the forward wall, each annular concave trough defining a first surface portion that curves radially outward and forward from a respective radially outward perimeter of the respective truncated conical deflector portion and a second surface portion that curves radially outward and rearward from a respective radially outward perimeter of the respective first surface portion wherein when one of the plurality of forward walls is secured to the forward end of the housing, the interior of the housing between the secured one of the plurality of walls and the adapter consists of a cylindrical surface. an adapter configured to attach to the muzzle accessory; and a sound suppressor configured to attach to the adapter, the sound suppressor comprising: an outer housing having a cylindrical interior and an open forward end; and a plurality of forward walls removably securable to the forward end of the housing and interchangeable with one another, each of the forward walls defining a through bore positioned along the forward wall to align with a central axis of each of the muzzles of the firearms when the forward wall is secured to the housing, each through bore conforming to the caliber of one of the firearms; an outer housing having a cylindrical interior and an open forward end; and a plurality of forward walls removably securable to the forward end of the housing and interchangeable with one another, each of the forward walls defining a through bore positioned along the forward wall to align with a central axis of each of the muzzles of the firearms when the forward wall is secured to the housing, each through bore conforming to the caliber of one of the firearms; wherein each forward wall defines a rearward surface configured to face an interior of the outer housing, each rearward surface defining a truncated conical deflector portion annularly surrounding the respective through bore of the respective forward wall and extending radially forward from a perimeter of the the respective through bore, each rearward surface further defining an annular concave trough encircling the respective truncated conical deflector portion and through bore of the forward wall, each annular concave trough defining a first surface portion that curves radially outward and forward from a respective radially outward perimeter of the respective truncated conical deflector portion and a second surface portion that curves radially outward and rearward from a respective radially outward perimeter of the respective first surface portion wherein when one of the plurality of forward walls is secured to the forward end of the housing, the interior of the housing between the secured one of the plurality of walls and the adapter consists of a cylindrical surface.
