Troops from D Company, 2nd Battalion, Royal Anglian Regiment have been evaluating the L351A1, the British Army's designation for the Mossberg 590M, as part of ongoing counter-UAS experimentation. The platform represents a tactical evolution in close-range air defense, offering ground units rapid-response capability against small unmanned aircraft systems operating at low altitude.

The 590M's box magazine-fed design provides enhanced capacity and faster magazine changes compared to traditional tube-fed shotguns, practical advantages in scenarios requiring sustained engagement.

As part of a layered defense strategy, the shotgun complements longer-range systems and electronic countermeasures, giving infantry units multiple options for defending against the evolving drone threat.

The British Army has been actively testing shotguns within its counter-UAS framework alongside other systems, recognizing that the modern battlefield requires varied kinetic solutions.

What's your take on shotguns as part of a drone defense toolkit? Are they effective? Have you seen counter-UAS shotgun systems in action or worked with such platforms?

    "Layered defense strategy" is the key here, and things will definitely not go well for any force which thinks this is all they need. It's like they say a CIWS isn't the last line of defense but the first line of damage control; if a unit is deploying shotguns against incoming drones, it better be because the machine guns and autocannons and anti-drone drones already stopped the bulk of the attack.

    I carried a Mossberg 500 in Iraq 2009-2010. I am a fan.


    I just don't understand adding a magazine to a pump shotgun. That is adding a failure point to a functioning weapon. With an extended barrel and extended tube, 7-8 shots is fine. If you have not defeated the drone or drones in your field of view in 8 shots, be on good terms with our Lord and Savior.

      I can see the appeal on a semiauto, but the added bulk and clumsiness of a box magazine just doesn't seem worth it on a pump shotgun in a world where stick type reloaders exist.
