The SIG Sauer Endure 30 .30 Cal titanium suppressor (SIG Sauer part no. ENDURE30) is a compact can built for hunting with a bolt-action rifle. Its core is 3D-printed titanium with internal geometry tuned for sound reduction, and the 6-inch length keeps it maneuverable in thick timber or on a long hike. A 5/8×24 direct-thread steel mount comes with it, and the HUB-compatible design lets the same suppressor move to other HUB-pattern mounts. A black high-temperature Cerakote finish with a topographic pattern covers the outside. It is aimed at hunters who want a short, rugged .30 caliber can.
