Features: The M16A2 5.56mm rifle is a lightweight, air-cooled, gas-operated, magazine-fed, shoulder- or hip-fired weapon designed for either automatic fire (3-round bursts) or semiautomatic fire (single shot) through the use of a selector lever. The weapon has a fully adjustable rear sight. The bottom of the trigger guard opens to provide access to the trigger while wearing winter mittens. The upper receiver/barrel assembly has a fully adjustable rear sight and a compensator which helps keep the muzzle down during firing. The steel bolt group and barrel extension are designed with locking lugs which lock the bolt group to the barrel extension allowing the rifle to have a lightweight aluminum receiver.
Background: The M16A2 rifle is a product improvement of the M16A1 rifle. The improvements are:
-
a heavier, stiffer barrel than the barrel of the M16A1;
-
a redesigned handguard, using two identical halves, with a round contour which is sturdier and provides a better grip when holding the rifle;
-
a new buttstock and pistol grip made of a tougher injection moldable plastic that provides much greater resistance to breakage;
-
an improved rear sight which can be easily adjusted for windage and range;
-
a modified upper receiver design to deflect ejected cartridges, and preclude the possibility of the ejected cartridges hitting the face of a left-handed firer;
-
a burst control device, that limits the number of rounds fired in the automatic mode to three per trigger pull, which increases accuracy while reducing ammunition expenditure;
-
a muzzle compensator, designed to reduce position disclosure and improve controllability and accuracy in both burst and rapid semi-automatic fire;
-
a heavier barrel with a 1 in 7 twist to fire NATO standard SS 109 type (M855) ammunition which is also fired from the M249 Squad Automatic Weapon (SAW). This further increases the effective range and penetration of the rifle cartridge. The M16A2 will also
-
shoot the older M193 ammunition designed for a 1 in 12 twist

Features: The M9 is a light weight, semiautomatic pistol manufactured by Beretta and designed to replace the M1911A1 .45 caliber pistol and .38 caliber revolvers. The M9 has redundant automatic safety features to help prevent unintentional discharges. It can be fired in either double or single action mode and can be unloaded without activating the trigger while the safety is in the "on" position. The M9 pistol has a 15-round magazine, and may be fired without a magazine inserted. This weapon can have the hammer lowered from the cocked, "ready to fire," position to the uncocked position without activating the trigger by placing the thumb safety on the "on" position.
Background: The 9mm Pistol Program was a Congressionally-directed Non-Developmental Initiative to standardize DoD with NATO and field one handgun for all United States armed services. Beretta of Italy was awarded a multi-year contract for delivery of over 500,000 pistols. The contract award stipulated that production of the weapon must transition from Italian to US production after two years. The US Army is the lead service in this program
