1. A firearm suppressor comprising:
a coupling mechanism configured to attach the firearm suppressor to a muzzle of a firearm;
an outer cylinder defining a longitudinal axis;
an inner cylinder having an inner chamber, where the inner cylinder is disposed at least partially within the outer cylinder and defines an outer chamber with the outer cylinder, where the outer chamber is disposed between an inner surface of the outer cylinder and an outer surface of the inner cylinder;
a first reverse flow pathway that is fluidly coupled with the inner chamber adjacent an end of the inner chamber that is opposite the coupling mechanism, and where the first reverse flow pathway has a first length and comprises a reverse section and a forward section; and
at least a second reverse flow pathway having a second length and comprising a reverse section and a forward section, and where the first reverse flow pathway is fluidly independent from the at least second reverse flow pathway.
