I want to replace the flash hider on my Colt 6920. How difficult is it to remove the factory-installed flash suppressor?
Assuming you have the appropriate tools and knowledge, removing a flash suppressor from a Colt AR-15 is not difficult. The first step is to remove the front sight assembly, which will give you clear access to the muzzle device. Next, using a barrel wrench or similar tool, loosen and remove the device. Finally, unscrew the crush washer from the threads on the muzzle, and be sure to save it for re-installation.
With that said, it’s important to note that many jurisdictions have regulations regarding the modification of firearms, so be sure to check local laws before proceeding. Additionally, altering your firearm in this way may void its warranty. So please exercise caution and consult with a qualified firearms specialist before proceeding.
