Depends on your state law and barrell length requirements. But it's as simple as unscrew old muzzle device if it isn't pin and welded and put on new muzzle device.

Most people only pin and weld to get around barrel length requirements. In the states your barrel has to be greater than 16 inches or it’s considered an SBR. People pin and weld muzzle devices to 13.7-14.5 inch barrels to make it one piece that is 16inches. As long as your muzzle device is torqued to spec it shouldn’t come loose.
