The Lightweight Ring Mount (5747) is a lightweight gunner’s platform designed specifically for the Landing Craft Air Cushioned (LCAC) hovercraft. It comprises of a weapon station with frontal protection on a geared slewing ring.

The LRM is designed to provide a defensive rotating weapon station with limited ballistic protection. The L47A1 gun mount that is fitted to the LRM accepts the 7.62mm L7A2 GPMG but has a reversionary mode so that it also accepts the 5.56mm L110A2 Light Machine Gun.

The weapon station is driven by a simple manual gearbox mounted on the LH side of the traversing ring. The gearbox may be disengaged to allow the gunner to quickly swing the weapon station through large angles of arc onto the target area. Fine final adjustment in traverse can then be made using the gearbox.

Protection is via a front lightweight armour panel shield.

The PWS is fully supported with NATO codified components.
