The Liberty Precision Machine (LPM) Anthem-S2 QD is the quick-detach version of LPM’s standard-length .30 caliber rifle suppressor (Liberty Precision Machine part no. LPM-10015). It comes fitted with a Rearden Atlas mount and includes two muzzle devices, an LPM Eclipse flash hider in 1/2-28 and an LPM Liberty Bell muzzle brake in 5/8-24. The baffle stack is the refreshed Anthem 2 design, with progressive spacing tuned along the tube for sound reduction, strength and low blowback. With a device for each common thread pitch in the box, one can moves between a 5.56 carbine and a .308 without a trip back to the parts counter.
