This is the Bushmaster Predator .223/5.56mm 20" Upper Receiver/Barrel Assembly. Adapted from the very accurate and successful 24" Varminter, the Predator Upper Receiver/Barrel Assembly's 20" Fluted Extra Heavy Non-Chrome-Lined Barrel is button rifled 1 x 8" to stabilize the heavier 69-77 grain bullets that a predator hunter/caller 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; 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) and B.M.A.S. 1/2" Mini-Risers to add scope height for correct sight picture and comfortable cheek weld.
