I'm getting ready to install a free-float quad rail handguard
to my CMMG upper. If I understand correctly, I'm going to need to R/R the front site and the flash hider to install the new handguard.
My only question before I begin is if the original peel washer on the flash hider is reusable, or if I need a new one before reinstalling. (This is the standard "A2 Flash hider installed with Peel washer" that came with the upper.) If it needs to be replaced, where might I order one? (IIRC, "crush" washers need to be replaced, but I'm not familiar with "peel" washers)
