That, my frenz, is an itty bitty damned .30cal rifle suppressor. It cost me all of $450 brand new and there was no tax stamp involved. The lack of an NFA stamp and the 5 month wait before I can try it out are both because it's in South Africa with many more of my belongings. Over there you can just make or buy a can with no hassles whatsoever. Folks over there would really rather that you do use a suppressor. Sigh. For -20dB, 2" WIDE and 5" wide you would be hard pressed to find anything more compact that's as effective. For the $$$, I don't think that's findable at all in the USA. Wish we could get them here.
