About Us

Industry Leading Innovation:
Since 1985, GSL has designed suppressed weapons systems that are used by most Government agency units throughout the world and designed advanced systems to ensure their safety and protect their hearing. In addition, we have worked with a wide range of local, state and federal Law Enforcement and Government agencies that depend on our innovative, durable and proven designs.

For over 30 years GSL has continued to lead the charge on product design, engineering, and patents – all while continuing to manufacture high-end suppression devices for the industry at large.

Our Founder
Greg received his first suppressor design patent in the early 1990s for the Helical Suppressor and was

featured on the cover of Machine Gun News. Since then he has received numerous other patents for various products and designs. He is a true pioneer and innovator in the world of suppressor technology having designed and developed over 66 suppressors for the military, law enforcement, and civilian markets.
