The MT6601 combines Colt’s Match Target series pedigree with a 20-inch HBAR profile and a 1:7 twist, offering proper 5.56mm NATO chambering as indicated by the "C MP 5.56 NATO 1/7 HBAR" barrel stamp. The direct-impingement, semi-automatic action is paired with A2 iron sights for a classic, proven setup.
This example reflects Ban-era configuration: an unthreaded, crowned muzzle and no bayonet lug, along with the fixed A2 carry handle upper. It also retains the two-piece screw-type front pivot—another hallmark of this period. The A2 front sight post sits in a triangular base, with the A2 rear sight integral to the carry handle.
The rifle wears round, ribbed A2 rifle-length polymer handguards and a fixed A2 stock with trapdoor buttplate and sling loop, plus an A2 pistol grip. The lower is rollmarked "MATCH TARGET MATCH HBAR CAL. .223," and the CMH-prefix serial further situates it within the era. Controls include a manual safety, and the length of pull measures 13.5 inches.
Colt’s "C MP" stamp verifies magnetic particle-inspected barrel steel, and the forward assist, brass deflector, and ejection port cover round out the A2 features. Capacity is 20+1, and this rifle includes one USGI-pattern 20-round aluminum magazine.
