ISDEF 2019: Flex Force’s Stabilizing Mount and RC Option

    Flex Force Enterprises (formerly Radio Hill) is more widely known for their counter UAV handheld DroneBuster device but the company also makes machine gun mounts that are currently in use by the U.S. Government. Their ASP-Land and ASP-Maritime are gyrostabilized mounts that are designed to be used in both a manual operator role and in a remote-controlled capacity as well. Although most of the photographs of the mount itself show it with a .50 BMG M2 Heavy Machine Gun, it can be configured for any particular platform that a client wants. This is done via a mounting bracket that serves as a ‘sled’ that can have proprietary bolts affixed in it allowing practically any NATO or Soviet-bloc weapon system to be mounted to it.

    But what truly sets the system apart from other mounts on the market today is the gyrostabilized capability. Mounted on the back of the receiver is a set of grips that extend beyond the spade grips of the M2 Machine Gun. These incorporate a trigger bar and integrated central safety that allow for traditional firing of the weapon via triggers in the mount spade grips. But on the front of these spade grips, where the user’s thumbs would rest are controls on the left and right grips. The left grip is a simple button that when pressed allows the mount to have a complete range of motion without any resistance. This allows the mount to be traversed and elevated rapidly. However, when a user’s left thumb comes off the button, the mount locks in and doesn’t allow any movement at all. On the right spade grip is a small joystick that falls in a natural position of the user’s right thumb. This joystick is for micro-movements which allow the machine gun to be traversed and elevated ever so slightly. This joystick can also be adjusted for sensitivity and even for reversing the pitch.

    An additional feature of the mount is its ability to slowly drop to a high port position if commands are immediately discontinued. So if a gunner has to quickly leave his position to attend to an urgent matter, the entire contraption slowly pushes itself down instead of being possibly jerked around by being let go.

    Also on display was the RC option, which consists of a simple user interface that plugs into the mount itself, and uses a day/night optics setup which allows the user to aim.
