The Vermin SMG utilizes a downward pointed recoil force together with an inline design, moving barrel to line with the shooters shoulder and hand to reduce the amount of recoil as well as muzzle climb. This greatly enhances the weapon's accuracy.
The Vermin is a SMG chambered for the .45 ACP round. It is fired from a 30 round magazine. It is the mainline Personal Defence weapon used by NATO forces. It is the gold standard in a PDW. Stopping power is where it excels: the larger .45 ACP bullet, coupled with the high cyclic rate, is capable of cutting close range targets in half. The Vermin is likely one of the best PDWs in the Arma world. It can mount all rifle optics and a Suppressor. The Vermin´s action is an articulated mechanism which allows the bolt and an inertia block to move downward into a recess behind the magazine well. The theory is that at the end of this travel, recoil energy is transmitted downward rather than rearward. On return, however that downward force is negated by upward force. Unlike its 9mm counterparts, it cannot use the .45 ACP handgun magazines like the PDW2000 or the Sting SMG.
