In my experience they can only help. Every rifle build (well most) is different and you can't know what it would feel like if the gas was tuned until you go ahead and tune it. I had an AR10 that felt like it was double tapping because it was so over gassed. The buffer would bottom out in the tube hard enough that I had to check the rounds in the magazine to be sure it wasn't going off twice. Most rifles won't be this far off but it was amazing how the rifle went from obnoxious to pleasing as I got the gas block tuned. To each their own. I like them.
