The SIG Sauer Endure 30 is a titanium suppressor rated for .30 caliber rifles (SIG Sauer part no. ENDURE30). It measures 6.0 inches long, compact enough to keep a hunting rifle manageable in the field. The can attaches with a HUB-compatible direct-thread mount cut 5/8-24, the common pitch on .30 caliber barrels. Because the mount follows the HUB pattern, it can be swapped for another HUB-compatible mount if your rifle changes. It suits hunters and shooters running .308 Winchester or 7.62 NATO rifles who want a light, short titanium can.
