ABSTRACT:
A dually-adjustable device for firearms is provided which is attached to the muzzle of a firearm to stabilize the muzzle and to suppress the flash during firing. The device is dually adjustable to counter both the magnitude and direction of firing forces. The device is further adjustable to individual firing characteristics as well as varying powder loads in ammunition. The device includes a cylindrical-shaped main body with at least one surface opening. One end of the main body attaches to the muzzle; the main body can be rotated about the longitudinal axis of the muzzle. The device further includes a cap with a gas-restricting opening which attaches to the other end of the main body. This gas-restricting opening in the cap causes a portion of firing gases to back up and flow through the surface opening thereby causing force in the direction of the opening which serves to stabilize the muzzle. A preferred cap comprises a frustum-shaped portion which narrows towards the firearm. The frustum portion increases the stabilizing effects of the device and suppresses muzzle flash. The cap is adjustable longitudinally, i.e., inward and outward, across the surface openings, to control the gas flow through the surface opening and thus the magnitude of the stabilizing force. Rotation of the main body and thereby the circumferential disposition of the surface opening controls the direction of the stabilizing forces. Indicia are disposed on the main body so a user can rotatably adjust the position of the surface opening for left and right-handed firers. Too, indicia are provided on the cap to assist a user in locating or relocating a desired or previously used cap position. The device is readily adjustable in the field or on the firing range without carrying spare parts or replacement items.
