Ase Utra Oy from Suomi Finland have been manufacturing sound suppressors for hunting, sports and professional use since 1994. Their usual production exceeds over 10,000 units per year and they state that they are one of the world’s largest manufacturers of sound suppressors. Their suppressors are not available in the United States and some other areas due to import regulations and restrictions, but it may still be of interest to TFB readers to see what is going on overseas in the development of suppressors. Nobody’s got an MP7 anyway…
