Built exclusively for Cabela's by Colt Competition, the Competition Series .223 Rem./5.56 NATO Semiautomatic Tactical Rifle was born for a good shoot-off. With a guaranteed sub-MOA accuracy at 100 yds. using quality ammunition and appropriate optics, it's not hard to see why. The 16" HBAR-contour, 4150 chromoly steel free-floating barrel has been proof-fired and air-gauged to precise bore dimensions. It comes equipped with a standard mil-type A2-style birdcage-vented muzzle brake. Threaded barrel accepts most standard-sized muzzle devices. The 1:8 rate-of-twist button rifling is optimized for 55- to 77-gr. bullets. Other highlights of this tack-driving machine include a gas-operated, direct-impingement system and smooth Colt 6-lb. target trigger with coated parts for long service life and consistent pull. Mil-type folding trigger guard allows use with thick winter gloves. Rifle comes equipped with a M4-style, six-position adjustable stock with steel sling loop; A2 military-style polymer grip; mil-type standard charging handle; five-slot, adjustable Picatinny handguard rail; 12" CNC-machined aluminum float-tube handguard; front swivel stud; and aluminum 30-round magazine. Upper and lower receivers are forged in USA from 7075-T6 mil-spec alloy. Upper receiver has 13-slot Picatinny rail. Rampant Colt and stylized "C" Colt logos on left side receiver. Mil-spec diameter receiver extension tube. Includes Colt cantilever scope mount, padlock and chamber flag. Manufacturer's one-year warranty.
