THE AP5 or “Apparatus Pistol”, is a Semi-Automatic Roller-Lock Delayed Blowback Action firearm based and built off of the original and historic design from the 1970s. The roller-lock platform has been widely respected as the preeminent design for over 50 years. Adopted for use across the globe, no other firearm of its type has been more successful. These firearms are imported from the MKE manufacturing facility in Turkey. All AP5 firearms are chambered in 9×19 mm and have a Cold Hammer Forged Chrome Molybdenum Vanadium Barrel with a 1:9.8” twist. The AP5 barrel has a 3-lug quick attachment and 1/2×28 threaded end for suppressor mounting options.
