Used Colt AR-15 A2 HBAR Sporter .223 – 20-Inch 1:7 Heavy Barrel, Pre-Ban R6600

This Colt AR-15 A2 HBAR Sporter is a classic commercial A2-pattern rifle chambered in .223 Remington. Built around a 20-inch heavy-profile barrel with a 1:7 twist, it features a fixed carry-handle upper, fully adjustable A2 rear sight, forward assist, brass deflector, rifle-length handguards and a fixed A2 stock. The rifle closely follows the visual profile and handling characteristics associated with the M16A2, while remaining a factory semi-automatic Colt sporting model.

The lower receiver is roll-marked “AR-15 A2 HBAR Sporter, Cal. .223” and bears serial number SP236058. Based on comparable Colt R6600 rifles in the SP229,000–SP237,000 range, this example was likely manufactured during the late 1980s and appears to qualify as pre-1994 production. A definitive manufacture date should be confirmed through Colt’s serial-number lookup or an archive letter before making legal or compliance representations. 

This example remains in very good used condition with light handling marks and normal operational wear. It retains the period-correct fixed stock, A2 pistol grip, carry-handle sights, heavy barrel, birdcage-style flash suppressor and bayonet lug. One detachable magazine is included.
