Patent attributes
A double helix firearm sound suppressor having a front portion with a front chamber, a rear portion with a rear chamber, and a hollow central core in the front chamber. Hollow projections extend from the hollow central core into the front chamber, wherein interiors of the hollow projections communicate with an interior of said hollow central core. The hollow projections form one or more helical pathways for propellant gases in one direction around the hollow central core and form one or more helical pathways for propellant gases in an opposite direction around the hollow central core. Openings in the hollow projections allow propellant gases to flow from the interior of the central core into the front chamber. The double helix configuration greatly increases the surface area for dissipating and suppressing sound.
