M16A3 Rifle, NSN 1005-01-367-5112 (Very Rare)
The M16A3, which was introduced in 1994, is basically an M16A2 with full-automatic capability and optional M4A1-style Rail Interface System (RIS). The M16A3 and the M16A4 are identical in appearance to the M16A2, but both have the modular upper receiver. The M16A3 is capable of fully automatic fire, like the M16A1, while the M16A4 uses the M16A2's three-round burst mechanism. Additionally, several types of optical sights have been developed for the modular upper.
M16A4 Rifle, NSN 1005-01-383-2872, LIN R97175 (In Common Usage).
The M16A4 is identical in appearance to the M16A3, but can fire single shots or 3-round bursts (no full auto). The M16A4 Rifle is a standard M16A2 Rifle with a flat top upper receiver and detachable carrying handle. The flat top upper receiver has an integral rail that will be utilized (when the carrying handle is removed) to mount optical devices to the weapon. The M16A4 Rifle in combination with the M5 Rail Adapter forms the Modular Weapon System (rifle version) which provides soldiers the flexibility to configure their weapons with those accessories required to fulfill an assigned mission. There are no differences between the internal dimensions of the M16A2 Rifle and the M16A4 Rifle.
The COEI / BII Listings and Component Hand Receipts on ArmyProperty.com are valid for these two rifles.
