Abstract: A remote trigger actuator, including a driver, a shaft coupled to the driver, the shaft including a central axis, a proximal end, and a distal end opposite the proximal end, and a cam coupled to the shaft proximate the distal end, the cam including a first end and a second end opposite the first end. Wherein rotation of the shaft about the axis causes the second end of the cam to engage a trigger of the firearm thereby discharging the firearm. The trigger actuator is configured to be mounted to the firearm.

Abstract: A muzzle attachment for a shotgun is disclosed including a first portion that has a first end, a second end, a central axis extending from the first end to the second end, and a through bore extending from the first end to the second end, concentric about the axis. The muzzle attachment also includes a second portion having a pair of opposing extensions defining a gap therebetween. Each extension has a base adjacent the second end of the first portion and a distal end extending away from the base. Additionally, the gap has a narrow end adjacent the base, a wide end adjacent to the distal end, and a pair of opposing lateral sides extending along a projection of the axis. Each of the sides includes a webbing disposed at the narrow end; wherein each webbing has an inner surface, an outer surface, and a radial thickness which tapers from the narrow end to the wide end.
