Sage Prototype Semi-Automatic 37mm Grenade Launcher

Sage have developed a very cool 37mm semi-auto magazine-fed grenade launcher (although 37mm rounds are only manufactured with less-lethal payloads). It is surprisingly compact. This is in part because it ejects upwards and has a rebated rim (the rim is much smaller than the cartridge diameter).

  • Actually, I was thinking that I could take over the *whole* world with that thing…

  • What’s the light for? Seems there needs to be extra stuff on everything these days.

    Oddly reminds me of an old CO2 powered CS gas pistol I picked up a few years back.
