10.5" 9mm Parkerized M4 Barrel AR15 Upper Assembly with 10" Rail and A2 Flash Hider
Pistol caliber carbines first appeared soon after metallic cartridges became common. These were developed as "companions" to the popular relovers of the day, firing the same cartridge but allowing more velocity and accuracy than the revolver. These were carried by cowboys, lawmen, and others in the Old West. The primary advantage of a carbine over a pistol using the same ammunition is controllability. The combination of firing from the shoulder, longer sight-radius, 3 points of contact (firing hand, support hand & shoulder), and precision offer a significantly more user-friendly platform. The longer barrel can offer increased velocity and, with it, greater energy and effective range due to the propellant having more time to burn.
