The FAXON URSSB556-SS-MB ARAK21 is a compensated AR upper assembly listed with a 16-inch barrel and 5.56 chambering in the model name. It is presented as a compensated upper intended for shooters assembling a mid- to long-range AR platform; the compensator is intended to help manage recoil and muzzle rise.
