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 barrel nut wrench. First, remove the flash hider from the package and hold it up to the barrel of your gun. Mark where the flash hider stops on the barrel with a marker or piece of tape.
Next, use the barrel nut wrench to loosen the barrel nut until it’s loose enough to remove by hand. Pull the barrel out of the receiver and set it aside. Slide the new flash hider onto the barrel and make sure it’s aligned with your marks. Tighten the barrel nut with the wrench until it’s snug. You may need to use some pliers if you can’t get enough torque with the wrench.
Once the flash hider is tight, reinstall the barrel into the receiver and you’re good to go!
