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.
