US12680776 - Tuner attached to a muzzle brake or suppressor of a firearm

A muzzle brake having a tuner and allowing for micro-adjustments to the weight of the barrel of a firearm. Upon being fired, the weighted the barrel mitigates the effect on aiming by disruptive frequencies reverberating through the firearm. The muzzle brake can incorporate a muzzle brake and be positioned after the muzzle brake segment such that the harmonics of the muzzle brake segment can also be affected by the muzzle brake. Use of the tuner on a firearm can increase overall accuracy and affect the groupings of shots on target when compared to use of a firearm without a muzzle brake.

The patent describes a muzzle brake that incorporates a tuner, allowing for micro-adjustments to the barrel’s weight to enhance firearm accuracy by mitigating disruptive frequencies during firing. This design enables improved shot groupings compared to firearms without such a muzzle brake.

Claim 1

1 . A muzzle brake for a firearm comprising: a cylinder, wherein the cylinder houses a bore that allows traversal through the entire longitudinal length of the cylinder, wherein the cylinder further comprises one or more muzzle ports positioned along an exterior circumference of the cylinder; a first threading located on a first end of the cylinder; an interior threading, wherein the interior threading is located at the first end of the cylinder and is configured to affix the muzzle brake to a firearm; a second threading located on a second end of the cylinder, wherein the second end is on the opposite end of the cylinder from the first end, wherein the second threading traverses at least a portion of the circumference of the second end and configured to affix a tuner to the cylinder; and the tuner is configured to be rotated radially, which adjusts the length and weight of the muzzle brake. a cylinder, wherein the cylinder houses a bore that allows traversal through the entire longitudinal length of the cylinder, wherein the cylinder further comprises one or more muzzle ports positioned along an exterior circumference of the cylinder; a first threading located on a first end of the cylinder; an interior threading, wherein the interior threading is located at the first end of the cylinder and is configured to affix the muzzle brake to a firearm; a second threading located on a second end of the cylinder, wherein the second end is on the opposite end of the cylinder from the first end, wherein the second threading traverses at least a portion of the circumference of the second end and configured to affix a tuner to the cylinder; and the tuner is configured to be rotated radially, which adjusts the length and weight of the muzzle brake.
