Hughes Precision Products manufactures some of the quietest, well built moderators built today. Hughes also manufactures the highest quality adapters, thread converters and thread protectors available anywhere at any price. A suppressor, also known as a sound suppressor, silencer or sound moderator, is a muzzle device that reduces the acoustic intensity of the muzzle report and eliminates muzzle flash when a weapon is discharged, by modulating the speed and pressure of the gas from the muzzle, hence suppressing the muzzle blast. A silencer can be a detachable accessory mounted separately onto the muzzle, or as an integral part of the barrel.
