The Faxon HARMONIX® SENTRY .36 Cal Rifle Suppressor is engineered for shooters who want one rugged, do-it-all can that balances low backpressure, strong sound suppression, and dependable flash mitigation across popular rifle platforms. Constructed from Haynes® 282 high-temp superalloy and finished in a durable high-temp ceramic coating, the SENTRY is full-auto rated and purpose-built to stay consistent as things heat up. If you’re chasing a suppressor that runs clean, stays tough, and mounts the way you want, this is your move. Upgrade your build today.

Faxon Firearms has been manufacturing precision components in the United States since 2012. The HARMONIX® line is designed and built with the same expectation we hold for our barrels: repeatable performance, tight process control, and American-made confidence.

Why the SENTRY .36 Cal?

The SENTRY is built to cover a wide range of common rifle setups with a practical caliber rating and mounting flexibility. With a .36 caliber rating, it’s a smart choice for shooters running 5.56, .30 caliber, and .36-caliber class applications (including modern heavy-subsonic platforms). The internal design prioritizes a balanced approach to gas flow to help minimize harsh blowback and keep your rifle running smoothly.
