The plate connects a middle part of a second horizontal supporter(13) of the bar assembly and an end part of a third horizontal supporter(14). The first fixing screw fixes an upper part of the plate and the middle part of the second horizontal supporter of the bar assembly. The second fixing screw fixes a lower part of the plate and the end part of the third horizontal supporter. The first bearing is installed in the second horizontal supporter of the bar assembly and supports a muzzle brake. The second bearing is installed in the third horizontal supporter of the bar assembly and supports the muzzle brake. Covers are individually installed at both a right side and a left side of the first bearing and the second bearing and prevent the bearing from including foreign substances.
