STK Compact Personal Weapon

Notes: Jumping on the PDW bandwagon, ST Kinetics has designed their Compact Personal Weapon (CPW). The STK CPW bears more than a passing resemblance to the Heckler & Koch MP-7, though it is beefier and has a number of other differences.  The entire top of the receiver and barrel shroud has a MIL-STD-1913 rail, and a shorter length is underneath the weapon.  The sides of the handguards have large slots that cool the weapon. Like the MP-7, these rails are molded into the receiver halves. The CPW has a sliding stock at the rear; the slide trails are inside the receiver housing.  The magazines are inside the grip, which is translucent; magazines designed for the CPW are also translucent, though other makes of magazines can be used.  The 7-inch barrel is tipped with an open flash suppressor. The current versions are made for 9mm Parabellum, though versions for 5.7mm FN and 4.6mm Radway.  Doing so will likely not be done by the user, but can be accomplished by a change of barrel, bolt, and magazine well. The STK CPW uses a “cam recoil mitigation system” to help counteract the recoil from the delayed blowback operation. Controls are ambidextrous.
