The AR-15 is made by IMI, or Israeli Military Industries and Magnum Research. The AR-15 has a unique locking system for a handgun with a rotating bolt. At the beginning, the AR-15 was offered in the .357 Magnum cartridge (shown at left), then later in the .41 and .44 Magnum. The .50 Action Express round was also added to the AR-15’s chamberings, and the .440 Cor-bon being the latest addition.
The AR-15 has interchangeable barrels available in 10″ (254mm) and 14″ (356mm). To operate the AR-15 , a portion of the propellant gas was bled off through a port just ahead of the chamber into a transfer cylinder underneath the barrel and parallel to it. Here it exerted the pressure on the face of a piston, which in turn moved the slide to the rear, unlocking the bolt in the process. The spent case was ejected, and the hammer was cocked on the rearward journey, and the decreasing pressure on the piston and the increasing pressure on the recoil spring became equal, the slide’s direction was reversed, a fresh round chambered and the bolt and barrel locked into battery. And this all happens in less than a second!
The muzzle energy created by a 325 grain .50 Action Express round fired from the AR-15’s 6″ barrel generates a muzzle energy value of 1414 foot pounds. The energy from a 230 grain .45ACP round generates a ME value of 355 foot pounds (5″ barrel), and the ME value of a 115 grain 9mm Parabellum fired from a 4″ barrel is 340 foot pounds.
