Donny FL Moderators for the Umarex Hammer
The Emperor by itself is the best option. However, it is still going to be loud (takes the “bark” out of the report) because of the blow-by at the breech. To compare the loudness, make sure the Hammer is loaded (don’t dry-fire to compare). Have someone else fire the gun without the Emperor and then with the Emperor while you stand about 10 yards down range.
