Hi I`ve done my homework on muzzle brakes by reading old threads but can`t find anything on this so .... Has anyone of you tried Gentrys muzzle brake? It`s the only one that they say doesn`t increase the noice level. It almost sounds to good to be true but I e-mailed them and they said that it did raise the noice level, by one decibel! So some first hand info would be great. Rolf, Sweden.
