Description
The M16A2 represented an improvement over the A1’s finicky Vietnam-era design. With it came an updated stripped upper receiver. Although the carry handle and general profile remained the same as the A1 rifle, the A2 upper once again changed the rear sight aperture with a more robust and distance-adjustable assembly. The horizontal finger wheel returned for windage adjustments, and the aperture could be raised or lowered with a side-mounted elevation knob to accommodate specific shooting distances, up to 800 yards.
A shell casing deflector was added just behind the ejection port to reduce interference and injury to the shooter from spent brass. The M16A3 is a modified version of the M16A2, produced in small numbers and primarily issued to members of the SEALs, Seabees, and security units. The trigger assembly was modified in the A3 to provide full-auto fire. All other components — including the A2-style upper — remained the same.
