Abstract: Systems for providing an illuminated insert for a gun sight include an insert that is inserted into a gun sight. The insert can have an illuminator that provides a source of illumination to improve visual acquisition of the sight. The insert is secured in an opening in the sight by a locking feature that contacts portions of an interior of the sight to secure the insert into the sight. The insert can be secured solely by the mechanical interactions of the locking feature without any further techniques, such as adhesives or the like. The insert is not removable from the sight without the use of destructive techniques to ensure security of the insert.

Abstract: A cleaning head for a marine cleaning system used for cleaning a liquid submerged surface includes a body configured to be disposed adjacent to and moved relative to the submerged surface during use. The body defines at least one suction aperture being in fluid communication with a suction region adjacent the body. At least one support arm extends from the body, which support arm in turn supports a respective cleaning element including a scraping blade that is configured to cause material on the submerged surface to separate from the submerged surface and become suspended in the suction region during use. The material separated from the submerged surface is drawn away from the suction region through the at least one suction aperture. Each support arm extends flexibly from a respective junction with the body so that the cleaning element is supported in a spaced relation laterally away from the junction with the junction being disposed in an operatively forward direction of the cleaning element during use.

Abstract: A self-propelled gun system defining a recoil mitigation system comprises a chassis; a gun barrel and a chassis suspension system comprising a first wheel arm extending away from the chassis to a first wheel, the first wheel being rotatably mounted on the first wheel arm, the first wheel configured for engagement with a support surface.
