All KMC suppressors are manufactured in-house. Uncompromised Idaho quality is what you get when you buy KMC. We pride ourselves on making what we like to call the "Blue Collar Suppressor". It is a basic and high-preforming suppressor for the average person. Instead of spending obscene amounts of money on "full-auto rated" or "high grade titanium", we focus on getting simple hearing protection into the hands of the public.
