The Faxon CoreSync .36 Cal Removable Core Rifle Suppressor is a serviceable rifle can from Faxon Firearms rated for .36 caliber or less (Faxon part no. FF-SIL-R-RCA-36-01). It uses a 17-4 stainless steel body around a removable Faxon Harmonix .36 caliber core in Haynes 282 and finishes in nitride. The mount is HUB compatible, and a 5/8×24 direct thread HUB adapter ships with it. The larger bore rating makes one can usable across a wider range of rifles than a .30 caliber design.
