The R6601 pairs a 20-inch steel HBAR with a 1:7 twist to stabilize a wide range of 5.56 NATO projectiles. The barrel is threaded and marked C MP 5.56 NATO 1/7 HBAR, reflecting Colt’s proof and magnetic particle inspection standards for this model.
An A2 fixed carry handle upper provides the integrated rear aperture sight, with an A2 front sight post up front. The upper also includes a forward assist, brass deflector, and ejection-port cover, delivering the full A2 sighting and control layout.
The rifle uses classic A2 furniture: a fixed A2 stock with a 13.75-inch length of pull, A2 pistol grip, and round rifle-length polymer handguards. The aluminum alloy receiver set wears a gray/black anodized finish consistent with the Sporter Match HBAR line.
This semi-automatic, direct-impingement AR-15 runs standard detachable STANAG magazines and has a 30+1 capacity. Notable configuration details include the large two-screw front pivot pin and the MH serial prefix that denotes the Match HBAR line.
