Muzzle brake and method for manufacturing muzzle brake

Abstract

A method for manufacturing a muzzle brake for a barrel includes designing a capsule assembly including a cavity, arranging powder in the cavity in the capsule assembly, pressing the powder so that the powder and capsule assembly are joined together, and removing excess material that covers the opening for outgoing gas flows. A muzzle brake, a firing barrel and a firing device are also provided.

1 . A method of manufacturing a muzzle brake for a barrel, comprising
 providing a capsule assembly including a cavity,   arranging powder in the cavity of the capsule assembly ( 60 ),   pressing the powder so that the powder and the capsule assembly are joined together,   removing excess material covering an opening for outgoing gas flows.   
     
     
         2 . Method according to  claim 1 , wherein the powder is pressed using high pressure and heat. 
     
     
         3 . Method according to  claim 2 , wherein the muzzle brake is heat treated and hardened using Hot Isostatic Pressing when finishing a muzzle brake. 
     
     
         4 . Method according to  claim 1  wherein the capsule assembly includes an inner tube, a rear capsule, and a front capsule, where the inner tube, the rear capsule, and the front capsule are arranged together in an outer capsule. 
     
     
         5 . Method according to  claim 4 , wherein the inner tube includes threads. 
     
     
         6 . Method according to  claim 1  wherein the powder comprises refractory metal. 
     
     
         7 . A muzzle brake produced by a method specified in  claim 1 . 
     
     
         8 . A firing barrel comprising a muzzle brake according to  claim 7 . 
     
     
         9 . A firing device comprising with a barrel according to  claim 8 .
