POTD: S&W Model 76 Integrally Suppressed

    VSO Gun Channel posted this on their Instagram page. It is a rare integrally suppressed Smith & Wesson M76. It is a clone of the Carl Gustav M/45 SMG but this one is chambered in 9mm. I am curious to see how quiet this is. Does anyone know if the barrel is vented like an MP5SD? If so then it would make super sonic rounds sub sonic.
