Bushmaster Predator Upper .223 20" Black Fluted AR15

Bushmaster AR-15 Predator A3 Flat-Top Upper Assembly 5.56x45mm NATO 1 in 8″ Twist 20″ Fluted Barrel Chrome Moly Matte with Vented Free Float Handguard.

The Bushmaster Predator AR-15 A3 was adapted from their very accurate and successful 24″ Varminter, the Predator Upper Receiver’s 20″ Fluted Extra Heavy Barrel is button rifled 1 x 8″ to stabilize the heavier 69-77 grain bullets that a predator hunter would choose for bigger varmints and predators. This superb barrel features fluting for increased cooling and weight reduction; an 11 degree competition crown; 1″ diameter heavy profile under the handguard and a custom match hybrid chamber with a tighter SAAMI Spec headspace from the shoulder of the chamber to the bolt face, and longer chamber throat or “Leade”. This chamber accommodates 5.56mm ammunition without developing higher pressures encountered when firing 5.56mm ammo in a .223 chamber with shorter “Leade” (both calibers can be used safely).

This Upper is sold complete with Bolt, Bolt Carrier and Charging Handle to ensure positive lockup between bolt and barrel extension. The Predator Upper also features a Vented Tubular Aluminum Free-Floater Forend with Bipod Stud (free-floats the barrel from the barrel nut forward).
