These Bushmaster Carbines offer light weight, compact size, balanced swing weight, and great accuracy from their chrome-lined, chrome-moly steel barrels. A2 solid buttstocks, Bushmaster forged aluminum receivers, and carbine length "shorty" handguards round out the features of these versatile carbines. The M16A2 sight system is fitted - featuring dual aperture rear sights (windage adjustable to 1/2 M.O.A. and 1 M.O.A. for elevation, with a 300 - 800 meter range). In the A3 type carbines, the removable carry handle (included) has a rear sight graduated from 300 to 600 meters, but of finer thread pitch to yield 1/2 minute adjustments. Front sights are all of the elevation adjustable A2 front post type. The picatinny rail on the upper receiver of the A3 type carbines allows versatile attachment of a variety of sights, scopes or night vision optics. Shipped with a 10 round magazine, carrying sling, and operating and safety instruction manual.
