I recently bought a Remington 700 SPS AAC SD, which has a threaded barrel. So I'm looking for a compensator (or possibly a flash hider) for it. But is it a simple screw on and go, or is there much more to it than that? Should I have a gun smith do it? Are some brakes easier to install then others? Use lock-tight or no? Can y'all recommend a good brake? Use is for hunting mainly, but of course fun at the range as well.
