I know these aren't after-market, but maybe one of the after market manufacturers has something similiar....
Savage has designed a Muzzlebrake that can be rotated open and closed. Shoot it open when running a lot of rounds through it at the range....when hunting, close it.
The Browning BOSS system now has a CR attachment. CR stands for convention recoil and the muzzle blast/sound is also conventional.
That's very interesting. I wonder how long it will take for others gun makers who offer muzzle brakes to follow? Or an aftermarket muzzle brake to come along that will fit other guns besides Browning?
