The Colt AR6920 Upper (brand part number LE6920CK-NHG) is a factory Colt upper receiver assembly built around a 16.1-inch .223 Remington/5.56 NATO barrel with a 1:7 twist rate. Sold by Colt as a bare upper, this assembly ships without a handguard or sight installed, giving builders a genuine Colt receiver and barrel as the foundation for a custom handguard and optic setup. It does include a charging handle and bolt, so the core function of the upper is ready to go once a handguard and sighting system are added.
