The Liberty Precision Machine Anthem-S2 QD .30 Cal Rifle Suppressor (brand part no. LPM-10015) is the quick-detach version of the Anthem 2 series, a line refreshed for better performance, lighter weight and a lower price. Its progressive baffle design is tuned for maximum sound reduction for its length, maximum strength for its weight and low blowback on gas-operated rifles. It ships with a Rearden Atlas GEN 2 QD mount plus a flash hider and a muzzle brake, so one box covers two muzzle thread pitches on a rifle that moves between hosts.
