On the muzzlebrake, I'd like to eliminate, what I see as the needlessly long birdcage style flash suppressor. However, the barrel wouldn't look right, nor would the crown be protected with bare threads. So that leaves options of what to replace it with. A simple metric threaded device, that is hollowed out so that it goes 75% down the barrel before engaging threads would give the barrel that chopped look, without actually cutting it down. As for its surface appearance, that's another question. I would however like to be able to fire a shot through the scoped rifle and see the bullet hit (if possible) or at least have the scope remain on target, and that's where a muzzle brake would be desirable. No there isn't much recoil, but the gun does seem to jump up and to the left on each shot, requiring re-aquisition of the target in sights.
