I don't mind the recoil characteristics of my old Mosin Nagant. I did notice others at the range shooting me the old "harley sneer" whenever I would touch off a round in my SVT40, however. I could not tell any difference in the noise from either rifle, but I could detect a different and softer characteristic to the recoil impulse from the SVT40.
Now, when I use the Cooley compensator on my PTR91 at the range, the blast from that thing loosens my sinuses immediately. The shock wave is noticeable. Folks do complain about that. Same with AK74 brake... noise is noticeable, but the rifle is a pussycat, and very very light.
Only one time at a static range I observed a guy set up a 50 BMG with that multiport brake, and upon his first shot knocked another guy's rifle right off the bench, maybe 2 or 3 benches away. We all jumped up to stop the fight, but the guy with the 50 was ejected and told to never return with that rifle.
Brakes do have an effect on muzzle rise and perceived recoil. Yep. To differing degrees based on their design.
