For operators, collectors, and law-enforcement-minded shooters looking for a service-proven AR in ready-to-ride condition, this trade-in carbine blends classic Colt build quality with a practical factory-mounted illumination system. The balance of durable components and a user-friendly lighting package makes it a strong option for patrol-style or home-defense setups.

COLT AR-15A3 arrives as a 5.56 NATO carbine with a 16-inch heavy barrel and a 1:9 twist, serial number LBD014635.

Key specifications and field features

This semi-auto trade-in is chambered in 5.56 NATO (barrel marked accordingly, receiver stamped .223 Rem), giving you the common, widely available cartridge suitable for training, defensive use, and range work. The 16″ heavy barrel with a birdcage flash hider and bayonet lug on the underside provides a stable sight plane and sustained accuracy potential. The 1:9 twist supports a broad range of bullet weights commonly used in 5.56.

Controls and ergonomics

The rifle includes a multi-position collapsible stock, A2 front sight post, shell deflector, dust cover, and forward assist. A Picatinny rail tops the receiver with no rear sight installed, offering flexibility to mount flip-up sights, optics, or a combination. The bore is reported very clean with bright barrel finish and clear rifling—evidence of light use and good maintenance.

SureFire M500 weapon light system

The standout feature is the integrated SureFire M500 lighting system. This replaces the original forend and provides a larger flashlight on the right and low-output navigation LEDs on the left, each with its own pressure pad. There’s also a constant-on rocker switch and a rotary system-disable to prevent accidental activation. Note: the pressure pad for the main flashlight did not function during inspection, but the on/off switch operates correctly; the nav light pressure pad functions normally.
