Abstract:
1. A gas operating system for a firearm, comprising: a gas block comprising a longitudinal piston bore; a compensating gas piston at least partially disposed in the longitudinal piston bore, the compensating gas piston comprising a piston body that is movable along the longitudinal piston bore, a gas pressure relief valve disposed internally within the piston body; and a diverter portion extending into the longitudinal piston bore, wherein the compensating gas piston is movable along the longitudinal piston bore to selectively contact a stop end of the diverter portion; wherein as the piston moves along the piston bore in response to the pressurized gases from firing entering the piston bore, the relief valve of the piston enables excess gases to be diverted through the piston body to reduce pressure acting on the piston and reduces bolt velocity during cycling of the bolt.
