Suppression systems for firearms
The present disclosure relates to a suppression system for a firearm, including: a barrel having first and second portions, wherein a wall thickness of the second portion is less than that of the first portion; and an integrally mounted suppressor.
1 . A suppression system for a firearm, comprising:
a barrel having a first portion and a second portion, wherein: the first portion and the second portion define a bore configured to receive a projectile upon discharge of the firearm; and a wall thickness of the second portion of the barrel is less than a wall thickness of the first portion of the barrel; and
a suppressor comprising:
a first mount configured to be connected to a first end of the second portion of the barrel;
a second mount configured to be connected to a second end of the second portion of the barrel;
a cylindrical outer body connected to the second mount; and
a first baffle and a second baffle disposed within the outer body and defining an expansion chamber in fluid communication with the bore, wherein the first and second baffles are coupled to the outer body and the second mount so that the first and second baffles are configured to translate in relation to the outer body, and the translation of the first and second baffles in relation to the outer body urges the first mount toward the second mount.
2 . The system of claim 1 , wherein the urging of the first mount toward the second mount compresses the second portion of the barrel.
3 . The system of claim 1 , wherein the second baffle is configured to be threadably coupled to the outer body so that rotation of the second baffle in relation to the outer body causes the first and the second baffles to translate linearly in relation to the outer body.
4 . The system of claim 3 , wherein the rotation of the second baffle in relation to the outer body causes the first and the second baffles to translate in a first direction in relation the outer body, and produces a force on the outer body acting in a second direction opposite the first direction.
5 . The system of claim 4 , wherein the force on the outer body is transmitted to the second end of the second portion of the barrel by way of the second mount, and urges the second end of the distal portion of the barrel in the second direction.
6 . The system of claim 4 , wherein the force on the outer body places the outer body in tension.
7 . The system of claim 1 , wherein the suppressor further comprises a cylindrical inner can attached to the first mount and coupled to the second baffle, the inner can being configured to urge the first mount toward the second mount.
8 . The system of claim 7 , wherein:
the expansion chamber is a first expansion chamber; and
the suppressor further comprises:
a third baffle coupled to the second baffle, the second and third baffles defining a second expansion chamber in fluid communication with first expansion chamber;
a fourth baffle coupled to the third baffle, the third and fourth baffles defining a third expansion chamber in fluid communication with second expansion chamber; and
a fifth baffle coupled to the fourth baffle, the fourth and fifth baffles defining a fourth expansion chamber in fluid communication with third expansion chamber.
9 . The system of claim 8 , wherein the inner can, the second mount, and the fifth baffle define a fifth expansion chamber in fluid communication with the fourth expansion chamber.
10 . The system of claim 9 , wherein the first mount defines a sixth expansion chamber in fluid communication with the fifth expansion chamber and the bore of the barrel.
11 . The system of claim 10 , wherein the outer body, the inner can, the second mount, and the fifth baffle define a seventh expansion chamber in fluid communication with the fourth expansion chamber and the fifth expansion chamber.
12 . The system of claim 11 , wherein:
the fourth baffle, the fifth baffle, and the outer body define an eighth expansion chamber located radially outward of the fourth expansion chamber and in fluid communication with the third, fourth, and seventh expansion chambers;
the third baffle, the fourth baffle, and the outer body define a ninth expansion chamber located radially outward of the third expansion chamber and in fluid communication with the second, third, and eighth expansion chambers;
the second baffle, the third baffle, and the outer body define a tenth expansion chamber located radially outward of the second expansion chamber and in fluid communication with the first, second, and ninth expansion chambers; and
the first baffle, the second baffle, and the outer body define an eleventh expansion chamber located radially outward of the first expansion chamber and in fluid communication with the first and tenth expansion chambers.
13 . The system of claim 12 , wherein the suppressor further comprises an end cap connected to the outer body, wherein the end cap and the first baffle define a twelfth expansion chamber in fluid communication with the first and the tenth expansion chambers.
14 . The system of claim 1 , wherein: the first and second baffles define a bore configured to receive the projectile upon discharge of the firearm; and the bore defined by the suppressor is aligned with, and is in fluid communication with the bore defined by the barrel.
15 . The firearm of claim 1 , wherein the first end of the second portion of the barrel is a muzzle of the barrel.
16 . The firearm of claim 15 , wherein the first portion of the barrel is configured to be connected to a receiver of the firearm.
17 . A firearm comprising the suppression system of claim 1 .
