They used to sell an adapter on donnyfl website for the hammer but I believe it’s been discontinued or removed from the website last time I had looked. If it’s been removed from their line I imagine there were issues with it.
I bought the above adapter and the Emporer by Donny fl for my umarex hammer in .50 cal. It doesn't seem any quieter. Do I need to use a different shroud? All I did was install adapter and supressor and nothing else.
