I Have This Old Gun: U.S. M16A2 Rifle
The M16A2 rifle, developed by Colt, incorporated significant improvements over the M16, notably influenced by the U.S. Marine Corps. Key upgrades include a heavier barrel for M203 compatibility, a 'birdcage' flash hider designed to reduce dust, a brass deflector for left-handed shooters, and an improved drum-style rear sight. It also features a three-round burst fire mode instead of full-auto and was optimized for the M855 'green tip' cartridge.
