A novel wearable apparatus for stabilizing a firearm is described. The 'Third Arm' apparatus attaches to a tactical vest on one end, and the rail interface system of the firearm on the other end. The arm allows the user to move the firearm with minimum restrictions while providing complete counterbalancing of the firearm, removing the weight of the firearm from the user's arms, thus reducing arm fatigue and improving accuracy. The apparatus enables the use of unconventional weapons systems including high recoil firearms and skeletonized firearms. Third Arm provides a structure to distribute recoil forces and onto which recoil management systems can be placed to aid in shot consistency and reduce discomfort of recoil forces. The apparatus is adjustable for different sized users and different weight firearms.

Third arm weapon interface system

A solid rocket propellant grain having rocket propellant and a membrane in contact with the rocket propellant. The membrane includes a highly heat conductive pattern which affects the propellant burning rate through localized conductive heat transfer from the combustion zone and into the uncombusted propellant. Different geometries for the thermally conductive pattern produce different combustion results.
