COLT AR-15A3 — this specific example carries a solid parts set and the notable SureFire M500 Weapon Light system installed by the original agency. Shop this product

Overview and specifications

This COLT AR-15A3 is chambered in 5.56 NATO with a 16-inch heavy barrel and a 1:9 twist. While the receiver is stamped .223 Rem, the barrel is clearly marked 5.56 NATO — a common arrangement on service rifles. The rifle features a birdcage flash hider, bayonet lug on the barrel underside, collapsible multi-position stock, shell deflector, dust cover, and forward assist. A Picatinny rail on the upper receiver leaves room to mount a rear sight or optic.

Notable features and practical effects

The front sight is a standard A2 post — rugged and familiar to most shooters. The heavy barrel profile improves sustained accuracy and heat management during higher-round-count drills at the range. The 1:9 twist stabilizes commonly used 55–69 grain bullets in 5.56 NATO, making this carbine versatile for training and defensive loads.

SureFire M500 Weapon Light system

The installed SureFire M500 integrates a larger flashlight on the right side and low-output LED navigation lights on the left. Each light has its own pressure pad, plus a constant-on rocker and a rotary system-disable switch to prevent accidental activation. In this unit the red-navigation pressure pad functions normally; the flashlight pressure pad did not activate during testing, though the on/off switch still powers the lamp. The system eliminates exposed wires by replacing the standard forend.
