Faxon CORESYNC® MultiCal Kit No. 1 – Multi-Core Suppressor System

Overview

The Faxon CORESYNC® MultiCal Kit No. 1 is the most adaptable suppressor system we’ve ever built— combining three caliber-optimized cores under one serialized outer body. Under one transfer, you get the ability to configure for 5.56, .30 cal, and .36 cal applications using interchangeable internal cores, matching endcaps, and included direct-thread HUB mounts.

At the heart of every CORESYNC® is Faxon’s advanced 3D-printed Haynes 282® superalloy core, engineered for exceptional heat tolerance and structural integrity, paired with a precision-machined 17-4 stainless steel outer body built for hard use and high round counts.
