Abstract: A non-pyrotechnic disseminator includes a body portion with a cover; a first compartment adjacent to the cover that is configured to hold disseminating materials; a chamber adjacent to the first compartment; a disk within the chamber and adjacent to the first compartment; a flow control device adjacent to the chamber opposite the disk; a second compartment adjacent to the flow control device and including a pin; an actuating mechanism connected to the pin; a third compartment adjacent to the second compartment opposite the flow control device that is configured to hold compressed gas; and a seal separating the second compartment from the third compartment. Actuation of the actuating mechanism causes the pin to break the seal causing release of the compressed gas into the second compartment and through the flow control device in a predetermined delayed timing, and then causing the compressed gas to burst the disk thereby pushing the disseminating materials out of the body portion by rupturing the cover.

Abstract: An optic mount for a firearm allows a user to switch between a primary optic and a secondary optic, facilitating rapid target acquisition when a user switches between close quarter engagement and long range engagement. The base of the optic mount is securable to a firearm. A primary optic platform can be pivoted and linearly translated with respect to the base. The primary optic platform is spring biased toward the front of the base. An actuator mechanism rotates a secondary optic platform on the base from a spring-biased first orientation to a second orientation. When in the first position, the primary optic platform engages the actuator mechanism, causing the secondary optic platform to be rotated to the second orientation. When in the second position, the primary optic platform does not engage the actuator mechanism, allowing the secondary optic platform to rotate to the first orientation.
