I have purchased the flash hider and the crush washer. I have read on some threads to use a split washer. Any comments please. Thank you.
There are a few different ways to install a flash hider. The most common way is to use a gunsmithing tool called a muzzle brake wrench. This wrench fits over the muzzle of the barrel and has teeth that grip the flash hider to install it. Another way is to use vise-grips or a large pair of pliers. If you’re using this method, make sure to protect the end of the barrel with something soft like a cloth or towel, to avoid scratching it.
Finally, some flash hiders come with installation instructions. If yours does, be sure to follow them carefully. Improper installation can cause damage to both the flash hider and the barrel of your gun.
