Markings on the lower include "COLTS LAW ENFORCEMENT CARBINE" with the prancing pony logo and an LE-prefix serial, plus the magwell text "RESTRICTED MILITARY/GOVERNMENT LAW ENFORCEMENT/EXPORT USE ONLY." The barrel is marked "5.56 NATO 1/7" and shows proof/inspection stamps. These roll marks and barrel identifiers provide clear model, chambering, and production context.
The 16-inch steel barrel uses a 1:7 twist to stabilize a broad range of 5.56 projectiles. It is threaded and fitted with an A2 flash suppressor secured by a crush washer. A fixed A-frame front sight base is pinned in place, providing a durable front sight reference.
The flat-top upper includes a forward assist, brass deflector, and ejection-port cover, along with a T-marked top rail. Operation is semi-automatic with a direct-impingement gas system, and controls include a manual safety selector.
This rifle is outfitted with an aftermarket aluminum quad-rail handguard that terminates at the handguard cap behind the front sight base and provides numbered T/L/R reference positions. A BCM flip-up rear aperture sight is installed. The carbine wears a 6-position, collapsible, skeletonized polymer stock and an A2-style polymer grip, with aluminum-alloy receivers finished in black hard anodizing.
Chambered in 5.56 NATO, the rifle accepts detachable AR-15 pattern magazines and includes one Magpul PMAG Gen M2 MOE 30-round magazine. Capacity is 30+1. The configuration and markings make this a solid example of Colt’s LE6920 pattern with practical upgrades already in place.
