Colt AR-15A4 HBAR 5.56 NATO Semi-Automatic Rifle, 20-Inch Heavy Chrome-Lined Barrel, Carry Handle Sights
This Colt Defense AR-15A4 HBAR pairs the classic, rifle-length M16A4 configuration with a heavy, chrome-lined 20-inch barrel for durability and consistent accuracy. Built on forged 7075-T6 receivers and finished in hard-coat anodizing, it features a detachable carry handle, A2 iron sights, and a fixed A2 stock. An early-spec example with a “CAR” serial prefix, it represents Colt’s post-2002 production era and retains the clean, original factory markings enthusiasts look for.

The 20-inch chrome-moly-vanadium heavy barrel is chrome-lined from chamber to muzzle, proof-marked “C MP” to show Colt proof-testing and magnetic-particle inspection. Its 1:9 rifling stabilizes common 55- to 69-grain 5.56 NATO loads, while the 1/2-28 threaded muzzle accepts standard flash hiders or suppressor mounts.
A rifle-length direct-impingement gas system delivers smooth recoil and reliable cycling. The flat-top upper includes a detachable carry handle with dual-aperture rear sight, giving shooters authentic A2 sighting or a rail ready for optics once the handle is removed.
The HBAR’s forged 7075-T6 receivers wear a black hard-coat anodized finish that matches the fixed A2 stock, trap-door butt-plate, and ribbed polymer handguards. The factory A2 pistol grip and rear sling swivel complete the traditional service-rifle ergonomics.
With light use, clean metal surfaces, and a bright, sharp bore, this AR-15A4 stands out as a well-kept, early-run Colt Defense rifle—equally ready for the range or a dedicated spot in a Colt collection.
