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).

    I founded TFB in 2007 and over 10 years worked tirelessly, with the help of my team, to build it up into the largest gun blog online. I retired as Editor in Chief in 2017. During my decade at TFB I was fortunate to work with the most amazing talented writers and genuinely good people!
