Stabilizer brake for firearm

摘要

A muzzle brake and stabilizing device is provided for a firearm having a barrel, the barrel having a barrel axis, a muzzle, and a breech end. The muzzle brake comprises walls defining a first chamber adjacent the muzzle end of the barrel, the first chamber having a substantially closed end wall and side wall through openings. Walls defining a second chamber are proximate the first chamber, the second chamber has a substantially closed end wall and side wall through openings. Walls defining a third chamber are proximate the second chamber, the third chamber with a substantially open end and having side wall through openings. Walls defining an intermediate chamber are adapted to receive gases passing through the side walls of the first, second, and third chambers, the intermediate chamber with closed side walls and a substantially closed end wall. Walls defining a fourth chamber are proximate the end wall of the intermediate chamber, the fourth chamber having a substantially open end, and side wall closed end openings.

1. A muzzle brake and stabilizing device for a firearm having a barrel, the barrel having a barrel axis, a muzzle, and a breech end, the muzzle brake for engagement to the muzzle, the muzzle brake comprising:
a) walls defining a first chamber adjacent the muzzle end of the barrel, the first chamber having a substantially closed end wall with a bore opening and multiple side wall through openings; b) walls defining a second chamber immediately following the first chamber, the second chamber having a substantially closed end wall with a bore opening and multiple side wall through openings; c) walls defining a third chamber immediately following the second chamber, the third chamber with a substantially open end and having side walls; d) walls defining an intermediate chamber, adapted to receive gases passing through the side wall through openings of the first and second chambers, the intermediate chamber with closed side walls and a substantially closed end wall with a bore opening; e) walls defining a fourth chamber, proximate the end wall of the intermediate chamber, the fourth chamber having a substantially open end; and
wherein the walls defining first and second chambers extend partly into the intermediate chamber, and the open end of the third chamber terminates short of the closed end wall of the intermediate chamber;wherein the intermediate chamber includes an annulus portion and an end portion, and wherein the multiple sidewall openings of the walls defining the first and second chambers are in gaseous communication with the walls defining the intermediate chamber;wherein the chambers are axially aligned with one another and further including walls adapted to engage the muzzle so as to place the axis of the chambers along the barrel axis.
