The concussion created when using a brake on a shorter barrel rifle like you have sucks. I personally wouldn’t use one on anything under 18” and never in lanes with walls.
I used to shoot a .223 SBR with a brake and I would shoot it inside once in a while and every time I would shoot it the lanes on both sides of me would clear out. I quit using it indoors because it was so obnoxious.
