The Faxon CoreSync .30 Cal Removable Core Rifle Suppressor is a fully serviceable rifle can from Faxon Firearms (Faxon part no. FF-SIL-R-RCA-30-01). It pairs a 17-4 stainless steel body with a removable Faxon Harmonix .30 caliber core made from Haynes 282, a nickel-based superalloy built for heat. Faxon rates it for .30 caliber or less, lists it as full-auto rated with no semi-auto barrel restrictions, and finishes the body in nitride. The can is HUB mount compatible and ships with a 5/8×24 direct thread HUB adapter and a .30 caliber ported end cap. It suits a shooter who wants one durable can for .30 caliber and smaller rifles that can be taken apart and cleaned.

Key Specifications

• The caliber rating is .30 caliber or less, so it covers .308-class rifles and smaller bores.
• The tube measures 6.5 inches on its own.
• Length with the end cap is 6.75 inches, the installed figure before the mount.
• Weight is 16 ounces, reasonable for a steel-bodied can with a superalloy core.

• The removable core is Haynes 282, the same superalloy Faxon uses in its Harmonix Sentry line.
• The finish is nitride, a hard surface treatment for wear and corrosion resistance.
• The mount interface is HUB compatible, so it accepts common HUB-standard mounts.
• Faxon lists it as full-auto rated with no semi-auto barrel length restrictions.
• Maximum body diameter is 1.73 inches, which sets handguard and optic clearance.
