The Anthem 2 series of .375 caliber rifle silencers is an evolution of the original Anthem series silencers from Liberty Precision Machine LLC. With lessons learned through the development of our other product lines, we have refreshed the Anthem baffle stack to achieve better performance and lighter weight. No barrel length restrictions on any .30 caliber (or less) cartridge, 16" minimum barrel length on .338 and .375 caliber cartridges burning more than 75 grains of powder. Removable front end cap with 3/4 socket
