How to install flash suppressor and crush washer?

A step-by-step guide on how to install a flash suppressor and crush washer can be found here:

1. First, remove the old muzzle device by unscrewing it from the barrel.
2. Next, slide the new muzzle device onto the barrel. It should fit snugly.
3. Now, use a punch or a drill bit to create a hole in the center of the crush washer. The hole should be just big enough for the screw to fit through.
4. Put the crush washer over the end of the muzzle device and make sure it’s centered properly.
5. Screw on the flash hider or compensator until it’s tight against the crush washer. Make sure not to overtighten it.
6. That’s it! Your new muzzle device is now installed.
