Multiple caliber sound suppressor with adapter for use with muzzle accessory
View Patent ↗A system for installing a first muzzle accessory on a barrel of a firearm having a second muzzle accessory mounted thereto comprises an adapter configured to attach to the second muzzle accessory and a first muzzle accessory configured to attach to the adapter. The adapter serves to temporarily deactivate the second muzzle accessory when the adapter is attached to the second muzzle accessory.
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.
2 . The system of claim 1 further comprising a coupler configured to attach to the adapter, the sound suppressor configured to attach to the coupler.
3 . The system of claim 1 , wherein the adapter is configured to limit air flow within the muzzle accessory to between a projectile intake and a projectile outlet of the muzzle accessory, whereby the muzzle accessory functions as an expansion chamber for gas exiting the muzzle.
4 . The system of claim 1 , wherein the adapter comprises a sleeve configured to surround at least a portion of the muzzle accessory.
5 . The system of claim 4 , wherein the adapter further comprises a chuck configured to engage the muzzle accessory to secure the adapter to the muzzle accessory when the muzzle accessory is received within the sleeve.
6 . The system of claim 5 , the chuck comprising at least one cutout defined along the sleeve, and at least one movable segment member removably received within the at least one cutout.
7 . The system of claim 6 , wherein the at least one movable segment member defines a surface configured to mate with and engage at least a portion of at least one feature of the muzzle accessory.
8 . The system of claim 7 , wherein the at least one movable segment member is rotatably secured to the sleeve within the at least one cutout.
9 . The system of claim 7 , the chuck further comprising a fastener for securing the at least one movable segment member within the at least one cutout.
10 . The system of claim 9 , wherein the fastener is a threaded fastener.
11 . The system of claim 10 , wherein the fastener establishes an engagement with the at least one movable segment member and a frictional engagement with the sleeve.
12 . The system of claim 1 , wherein each forward wall defines a threaded outer surface adapted to threadably mate with an inner surface of the outer housing and at least one protuberance configured to be engaged for rotating the forward wall into and out of threadable engagement with the housing inner surface.
13 . The system of claim 12 , each protuberance being defined by a removable bolt positioned along a forward surface of the forward wall.
14 . The system of claim 1 , wherein the plurality of forward walls include forward walls having through openings conforming to each of a plurality of calibers.
15 . The system of claim 1 , wherein when the adapter is attached to the muzzle accessory and the sound suppressor is attached to the adapter with one of the forward walls secured to the outer housing, the outer housing defines a smooth and unobstructed cylindrical cavity from a forward end of the muzzle accessory to a rearward end of the secured forward wall.
