I cant imagine with just the umg supressor that is so rare that, that muffled sound would be obtained. There has to be something else involved. internal padding/washers etc.
Im going to make a ghetto silencer Steven Segal style in underseige with a pop bottle
No but really, theres no where I can find a UMG suppressor unless i get lucky in the classifieds. I have yet to come accross someone who has customized another make/model to fit. Curse g&g for that.
