If you remove the muzzle brake on the muzzle,
you can install a muzzle option with a 14mm reverse screw specification such as a silencer.
*Adjustable front / rear sight
The front sight can be adjusted up, down, left and right with a dedicated adjust tool.
In addition, the rear sight can be adjusted up and down by simply changing the position of the slide bar to lift the plate-shaped sight body.
