Revolving shotguns seized in Taiwan


Here is a very neat example of an improvised revolving shotgun displayed by police in Taiwan. This design makes use of a paintball marker as it’s receiver/fire control and is fitted with airsoft M4 rails & fore-grip. It appears several have been recovered from various drug related incidents suggesting illicit factory origin.

A similar pistol variation also appears to have been recovered. The drum assembly closely resembles others recovered from a large illicit factory raid in 2005.

These simple designs are entirely manually operated. A spring loaded ball bearing seated in the frame friction locks into a dimple beside each chamber which can be overcome when rotating the drum by hand. All fire from an open bolt / striker, in some examples assisted via a spring loaded ‘pump’ arm.

    i can already hear journalists yelling “paintball guns can be easily converted to shotguns!”

      I remember seeing on the now apparently defunct Impro Guns blog a 40mm grenade launcher made from a paintball gun…

      Anything is EASY if you know what your doing…

      You shoulda seen them during all that panic about the Liberator…. =D

    Sorry, I’m not sure I get it…
    The “open bolt” is actually a firing pin with some mass to give it momentum being manually locked to compress its spring after every shot… there’s no real bolt as we’re talking about a revolver, right?

      The ammunition source is a revolving cylinder, but the firing mechanism is a (manually) cocked bolt that fires from an open position. You can see on photos 4 and 5 the cocking lever that gets held in place by the trigger. After a shot, you manually index the cylinder and manually cock the bolt (I believe).

      Small correction. It looks like in 4 and 5 that they have an actual spring loaded slide that pushes back what I thought of as the cocking lever.

    Still a better shotgun than the KSG.

    Keep posting homemade firearm seizure stories, they’re some of the best custom firearms ive seen. The Australian jeweler who made those two MACs with the suppressors? Amazing!

    And yet this is somehow LESS fugly than the last Taiwanese revolving shotgun I saw:

    Though that’s debatable. Feel free to debate that, even I may disagree with myself on this.

    • bbmg

      Ah, but do they have a Beretta logo and are they made in the USA?

  • Madeline Gault

    Looks like an ARWEN launcher.

  • Joseph B Campbell

    Different. Still see safety issues that need to be addressed and I have not even held it yet!
