The M16 has a 500mm (19.75 inches) sight radius. The M16 uses an L-type flip, aperture rear sight and it is adjustable with two setting, 0 to 300 meters and 300 to 400 meters. The front sight is a post adjustable for elevation in the field. The rear sight can be adjusted in the field for windage. The sights can be adjusted with a bullet tip and soldiers are trained to zero their own rifles. The sight picture is the same as the M14, M1 Garand, M1 Carbine and the M1917 Enfield. The M16 also has a "Low Light Level Sight System", which includes a front sight post with a small glass vial of (glow-in-the-dark) radioactive Tritium H3 and a larger aperture rear sight. The M16 can mount a scope on the carrying handle. With the advent of the M16A2, a new fully adjustable rear sight was added, allowing the rear sight to be dialed in for specific range settings between 300 and 800 meters and to allow windage adjustments without the need of a tool or cartridge. Modern versions of the M16 use a Picatinny rail which allow for the use of various scopes and sighting devices. The current United States Army and Air Force issue M4 Carbine comes with the M68 Close Combat Optic and Back-up Iron Sight. The United States Marine Corps uses the ACOG Rifle Combat Optic and the United States Navy uses EOTech Holographic Weapon Sight.
The AK-47 has a 378mm (14.88 inches) sight radius. The AK-47 uses a notched rear tangent iron sight, it is adjustable and is calibrated in hundreds from 100 to 800 meters (100 to 1000 meters for AKM models). The front sight is a post adjustable for elevation in the field. Windage adjustment is done by the armory before issue. The "fixed" battle setting can be used for all ranges up to 300 meters. This "point-blank range" setting marked "П", allows the shooter to fire at close range targets without adjusting the sights. Longer range settings are intended for area suppression. These settings mirror the Mosin-Nagant and SKS rifles which the AK-47 replaced. Some AK type rifles have a front sight with a flip-up luminous dot that is calibrated at 50 meters, for improved night fighting. All current AK-47s (100 series), have a side rail for mounting a variety of scopes and sighting devices, such as the PSO-1 Optical Sniper Sight. However, their side folding stocks cannot be folded with the optics mounted.
