I too was in question of the brake,s ports direction. I was worried about it as well untill I fired it. You wont notice it. Shooting buddy shoots/sets up to my left or right as he doesnt complain.
The only thing I wish it had was ports on the top side to aid in muzzle jump. My HS model 10 has a Benny Cooley (sp) that (imo) does a better job...but Im not gonna change out the one that came with the model K..........least not yet..............
