B&T APC9-SD SMG

Based on the proven APC9, the APC9-SD is a sophisticated design that will enable the operator, anywhere under any circumstances, to deploy a fully suppressed carbine or submachine gun while using standard 9 mm ammunition. The APC9-SD has been designed to accept normal supersonic 9 mm FMJ and Hollow Point ammunition (> 7.5 g / 115 grs) but will reduce the velocity of this bullet down to subsonic levels. This makes having a stock of subsonic ammunition unnecessary and the risk of „Murphy“ interfering in operations when stealth in covert operations is a requirement. This could be the shooting of street lights, guard dogs, car tires and other forms of target interdiction. The two loudest sources of noise when firing a weapon are greatly reduced by the sophisticated design of the APC9-SD. One is the sound of the bullet breaking the sound barrier. This is remedied by the holes which are ported on the base of the barrel near the chamber. As part of the propelling gases escaping trough theses holes into the suppressor, the bullet will not be accelerated to supersonic speed. The second are the hot propelling gases leaving the muzzle of the weapon. This is prevented by the state-or-the-art suppressor integrated on the APC9-SD.
