Two years later, the company began producing .300 Blackout ammunition in both supersonic and subsonic loads.

Gemtech was instrumental in forming the American Suppressor Association (ASA), a nonprofit trade association "to further the pursuit of education, public relations, legislation, hunting applications and military applications for the silencer industry".

In July 2017, it was announced that Gemtech was purchased by firearm manufacturer, Smith & Wesson.
