Developed in the early 1980s, the M16A2's parameters were mostly driven by requests made by the United States Marine Corps. These requests included alterations to the stock and forearm, integration of an adjustable rear sight, closing off the bottom of the birdcage pattern flash hider, and swapping out the full auto fire mode for a three round burst mode. These were the signature weapon of the U.S. armed forces through the end of the Cold War and up to the War on Terror. This particular example is in "Grenadier" configuration, with an enlarged handguard acting as the mounting point for a M203 grenade launcher (more detail in Item B) and a flip-up ladder sight graduated to 250 meters, and a folding post and peep sight clamped to the carry handle graduated up to 400 meters. This combo served as the "big stick" of American infantry squads for decades, providing near-instant firepower while also allowing the grenadier to defend themselves if confronted by a threat unsuitable for a grenade. Elevation adjustable post and fully adjustable peep rear sights, with an A2 pattern flash hider on the "C MP 5.56 NATO 1/7" marked HBAR profile barrel with bayonet lug and aforementioned enlarged handguard. "C/M" is cast into the carry handle, with a round button style forward assist and casing deflector integrated into the upper, and a M16A2 marked lower with "SAFE"/"SEMI"/"BURST" markings around the right handed selector. Fitted with a checkered pistol grip and fixed buttstock. The bolt carrier is marked "C" and the bolt head "MPC", both matte finished. Both the safe and semi-automatic positions work as marked, with the internals configured to produce a two-round burst instead of the A2-standard three on the "BURST" setting.

Excellent, with 98% of the original matte black phosphate finish, with minor handling marks overall. The furniture is in equal condition. Mechanically excellent. NOTE: This weapon is a National Firearms Act (NFA), fully transferable Class 3, which is registered with the Bureau of Alcohol, Tobacco, Firearms and Explosives, (BATFE) under the provisions of 18 U.S.C. Chapter 44 and 27 CFR part 479.

Originally developed as part of the Special Purpose Individual Weapon program, the M203 has been a mainstay of American infantry for decades. Designed for compatibility with the 40mm rounds used by the M79, the M203 is primarily aluminum in construction, with a ribbed plastic grip cover on the sliding barrel, a safety switch inside the triggerguard, and a spring steel triggerguard that hooks on the magazine well of the host rifle. The mechanism is single action, cocking automatically as the barrel is closed, with a spring hook extractor for the spent casing.

Excellent, with 98% plus original matte black phosphate finish, showing minor handling marks overall.
