Need some help from some of you experts. I bought a Remington 700 mil-spec 308 and it has a flash protector on it. I would like to change out the flash protector to a muzzle break. Question is is this easy to do, are the threads the same on both. Do all breaks have the same threads or are there different threads? My plan is to take it to gunsmith, but wondering can I just order my break or is there different sizes and thread patterns? Any help is appreciated
