Sound suppressor with adapter for use with muzzle accessory

1. A system for installing a sound suppressor on a barrel of a firearm having a muzzle accessory mounted thereto, the system comprising:

an adapter configured to attach to the muzzle accessory, the adapter comprising:

a sleeve configured to surround at least a portion of the muzzle accessory;

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, 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, the at least one movable segment member defining a surface configured to mate with and engage at least a portion of at least one feature of the muzzle accessory, the at least one movable segment member rotatably secured to the sleeve within the at least one cutout;

wherein the sound suppressor is configured to attach to the adapter; and

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 barrel.

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 sound suppressor comprises a deflector integrally formed with a forward end wall of the sound suppressor.

4. The system of claim 1 , the chuck further comprising a fastener for securing the at least one movable segment member within the at least one cutout.

5. The system of claim 4 , wherein the fastener is a threaded fastener.

6. The system of claim 5 , wherein the fastener establishes an engagement with the at least one movable segment member and a frictional engagement with the sleeve.

7. An adapter for installing a first muzzle accessory on a barrel of a firearm having a second muzzle accessory mounted thereto, the adapter comprising:

a sleeve having an inner surface configured to surround at least a portion of the second muzzle accessory, the inner surface of the sleeve configured to block air flow through at least one vent of the second muzzle accessory, the sleeve defining a plurality of cutouts extending therethrough and a portion configured to attach to the first muzzle accessory;

a plurality of segments, each segment being receivable within a corresponding cutout of the plurality of cutouts, each segment defining an inner surface configured to mate with and engage a portion of the second muzzle accessory; and

a fastener for securing the segments within the corresponding cutouts in engagement with the second muzzle accessory;

wherein the segments are rotatably secured within the corresponding cutouts at circumferentially adjacent ends of the cutouts.

8. The adapter of claim 7 , wherein the sleeve is cylindrical and wherein the cutouts are arranged along a circumference of the sleeve.

9. The adapter of claim 7 , wherein each of the segments is freely rotatable in relation to the sleeve between a first position, in which the segment is partially removed from the corresponding cutout, and a second position, in which the segment is received within the corresponding cutout.

10. The adapter of claim 7 , wherein the fastener comprises a collar configured to surround and retain the segments within the corresponding cutouts.

11. The adapter of claim 7 , wherein the inner surface of the sleeve defines a stop configured to limit receipt of the second muzzle accessory within the sleeve.

12. An adapter for installing a first muzzle accessory on a barrel of a firearm having a second muzzle accessory mounted thereto, the adapter comprising:

a sleeve having an inner surface configured to surround at least a portion of the second muzzle accessory, the sleeve defining a plurality of cutouts extending therethrough and a portion configured to attach to the first muzzle accessory;

a plurality of segments, each segment being receivable within a corresponding cutout of the plurality of cutouts, each segment defining an inner surface configured to mate with and engage a portion of the second muzzle accessory; and

a fastener for securing the segments within the corresponding cutouts in engagement with the second muzzle accessory;

wherein each of the segments defines a threaded outer surface, and wherein the fastener has an inner threaded surface adapted to threadably mate with and engage the threaded outer surface of the segments to retain the segments within the corresponding cutouts.
