ROUNDSHOT | AIR BURST WEAPON
The 40mm Roundshot air bursting grenade launcher is a manually operated, multi-shot support weapon operated by one man. Originally designed to fire a wide variety of 40mm less-lethal (flash-bang, tear gas, baton etc) rounds produced by Alestex, it is has been redeveloped with an integrated optical system in a “full lethal” version that can fire most types of combat NATO 40mm LV ammunition, with a distinct focus on a specialist counter-defilation 40mm grenade.
The weapon is a hand-held weapon of bullpup layout, with polymer outer casing. It is cycled manually by pulling charging handles located at either side of the weapon, and fed from detachable box magazines.
The Roundshot fires 40 mm grenades that are set to explode in mid-air at or near the target. A laser rangefinder in the weapon's integrated optics are used to determine the distance to the target. The user can manually adjust the detonating distance by up to 10 feet (3.0 m) shorter or longer; the Roundshot automatically transmits the detonating distance to the grenade in the firing chamber. The grenade tracks the distance it has travelled by the number of spiral rotations after it is fired, then detonates at the proper distance to produce an airburst effect. These features make the Roundshot more effective than traditional grenade launchers at the task of hitting targets that are behind cover or dug into the ground.
In addition to the airbursting munitions, opportunity rounds may be used without the air bursting calculation effects. These include: Thermobaric, Flechette, Training, Non-lethal, Armor Piercing (50 mm armor penetration), and Door breaching grenades.
