The Faxon CoreSync .30 Cal Removable Core Rifle Suppressor is a fully serviceable can from Faxon Firearms for rifles chambered in .30 caliber or smaller (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. The finish is nitride, and the mount interface is HUB compatible. A 5/8×24 direct thread HUB adapter and a .30 caliber ported end cap come in the box. It suits a shooter who wants one durable can for .30 caliber and smaller rifles that can be taken apart and cleaned.
