US12723832 - Reverse thruster muzzle brake for firearms

The present disclosure presents a muzzle break for a firearm having two portions, each comprising corresponding curved baffles, a semicircular channel running the length of the brake, circular inserts, and clamping screw receptacles. Inserts for the bore hole where the gas pressure is highest are inserted into the portions before assembly, and each half of the brake comprises a machined clearance, such that when the brake halves are assembled there is a split machined clearance over the firearm barrel outside diameter. The two halves are fastened together, with alignment pin inserts inserted into machined slots before assembly, and the inner portion of the interior channel is threaded to mate with the threading on a firearm barrel. The muzzle brake is mounted to the firearm barrel by threading the inner portion of the interior channel of the brake onto the barrel to the point of the split machined clearance. Two clamping screws are used to clamp down the barrel end of the brake inner diameter onto the barrel outer diameter to secure the brake to the barrel.

The patent describes a muzzle brake system for firearms that features two portions with curved baffles and a semicircular channel, designed to be securely mounted onto the firearm barrel using alignment pins and clamping screws. This innovative design aims to enhance gas management and reduce recoil by utilizing dual exhaust ports and a threaded connection to the barrel.

Claim 1

1 . A muzzle brake system for a firearm having a barrel, comprising: a first portion comprising a plurality of curved baffles with dual exhaust ports, a plurality of machined alignment pin receptacles, a plurality of fastener receptables, a central semicircular channel corresponding to the longitudinal axis of the firearm barrel, and an aft portion of the channel with a larger interior diameter than an adjoining forward portion; a second matching portion comprising a corresponding plurality of curved baffles with dual exhaust ports, a corresponding channel formed in the center of the baffles, a plurality of corresponding machined alignment pin receptacles, a plurality of corresponding fastener receptables, and a corresponding central semicircular channel corresponding to the longitudinal axis of the firearm barrel, and an aft portion of the channel with a larger interior diameter than the adjoining forward portion, wherein the adjoining forward portion of the interior of the channel is threaded to mate with the threading on the firearm barrel; a plurality of alignment pins inserted into the corresponding machined alignment pin receptacles in each of the first portion and second portion; a plurality of fasteners inserted into the corresponding fastener receptables and securing the first portion to the second portion; a plurality of clamping screws that, when tightened, secure the aft inner diameter of the brake onto the firearm barrel outer diameter to secure the brake to the barrel; and a plurality of circular inserts inserted into the interior channel formed by the first portion and second portion. a first portion comprising a plurality of curved baffles with dual exhaust ports, a plurality of machined alignment pin receptacles, a plurality of fastener receptables, a central semicircular channel corresponding to the longitudinal axis of the firearm barrel, and an aft portion of the channel with a larger interior diameter than an adjoining forward portion; a plurality of curved baffles with dual exhaust ports, a plurality of machined alignment pin receptacles, a plurality of fastener receptables, a central semicircular channel corresponding to the longitudinal axis of the firearm barrel, and an aft portion of the channel with a larger interior diameter than an adjoining forward portion; a second matching portion comprising a corresponding plurality of curved baffles with dual exhaust ports, a corresponding channel formed in the center of the baffles, a plurality of corresponding machined alignment pin receptacles, a plurality of corresponding fastener receptables, and a corresponding central semicircular channel corresponding to the longitudinal axis of the firearm barrel, and a corresponding plurality of curved baffles with dual exhaust ports, a corresponding channel formed in the center of the baffles, a plurality of corresponding machined alignment pin receptacles, a plurality of corresponding fastener receptables, and a corresponding central semicircular channel corresponding to the longitudinal axis of the firearm barrel, and an aft portion of the channel with a larger interior diameter than the adjoining forward portion, wherein the adjoining forward portion of the interior of the channel is threaded to mate with the threading on the firearm barrel; a plurality of alignment pins inserted into the corresponding machined alignment pin receptacles in each of the first portion and second portion; a plurality of fasteners inserted into the corresponding fastener receptables and securing the first portion to the second portion; a plurality of clamping screws that, when tightened, secure the aft inner diameter of the brake onto the firearm barrel outer diameter to secure the brake to the barrel; and a plurality of circular inserts inserted into the interior channel formed by the first portion and second portion.
