The Liberty Precision Machine (LPM) Mach-S titanium suppressor is the standard-length .30 caliber can in LPM’s Mach series (Liberty Precision Machine part no. LPM-10018). LPM gave the Mach series the same baffle stack as the Anthem 2 series and built it in titanium, so the Mach-S matches the Anthem-S2’s 6.85-inch length at 9.0 ounces instead of 14.2. A 5/8-24 Rearden DTA Ti direct thread adapter comes with it. The finish is Graphite Black Cerakote. It sits between the short Mach-K and the long Mach-L, which makes it the all-round choice for a hunting or precision rifle where weight counts.
