As for installing the muzzle brake, if you don't live where they require the flash suppressor to be welded or pinned, it's just a matter of unscrewing the birdcage, installing a new crush washer, then installing the new brake. Specifics on the installation, such as torque and positioning, are generally included with instructions provided with the new brake. That's all there is to it.
Good Luck and good shooting.
