The Tar-21 is an Israeli bullpup assault rifle with a selective fire system. Bullpup rifles are configured in a layout in which the bolt carrier group is placed behind the pistol grip; this shortens the overall length but does not sacrifice barrel length. The T.A.R. 21 provides carbine length, but rifle muzzle velocity. The bullpup design is also used to minimize the silhouette of soldiers and maximize effectiveness in turning corners in urban warfare. This rifle features a full top rail with flip-up sights and a polymer handguard, and the body is made from a high-strength ABS. This fires at about 330fps and has a 300rd hi-cap magazine.
