The MT6601 configuration pairs a 20-inch HBAR with a 1:7 twist to support a wide range of 5.56mm NATO loads. The barrel carries the correct Colt markings: "C MP 5.56 NATO 1/7 HBAR." It is a plain-crown, unthreaded muzzle consistent with the post-ban setup.
The upper is the fixed A2 carry-handle type and includes a forward assist and case deflector. Sighting is classic A2: a front sight post and a rear sight in the carry handle with the A2 elevation drum.
Furniture follows the A2 pattern with a fixed polymer stock (13.5-inch length of pull), A2 pistol grip, and rifle-length round ribbed handguard. The rifle uses the AR-15 direct-impingement, semi-automatic action with a manual safety selector.
This model uses the STANAG magazine interface and is marked with Colt proof and inspection stamps, including C MP and the Colt rampant pony over globe. It is cataloged under Colt part number MT6601 and was produced during the 1994–2004 AWB era.
