How to permanently pin a flash hider? Can I pin a flash hider by myself to be compliant without NFA? What is the process? Thanks.
The easiest way to pin a flash hider is to first remove the muzzle device from the barrel. Next, using a small Allen wrench, loosen the set screws on the Flash Hider. Gently unscrew the Flash Hider until it is loose enough to slide off the muzzle. After removal, inspect the muzzle threads to be sure they are not damaged. If they are in good condition, you can now install the pinning device of your choice. We also recommend applying a drop or two of the thread locker onto the set screws before final installation for extra security. Now that you have your flash hider unthreaded and ready to receive a pinning device, it’s time to select which method you will use.
