If you’re in the market for a new rifle, this review will help you make a decision as to whether the Tavor Bullpup or an AR-15 carbine is better for your needs as a shooter. Both are 5.56 semi-automatic civilian versions of military rifles, the TAR 21 and the M16 and variants, respectively. The M16 has seen service since the Vietnam War, and its variants are used by military, law enforcement, and private security in over 80 countries. The TAR 21- Tavor Assault Rifle, 21st Century- has seen combat in the hands of the Israel Defense Forces since 2001, and units in 24 other countries, including the United States, have adopted TAR 21 for use in some capacity. The Tavor has only been available in the US civilian market for a few years, but it is quickly gaining popularity. The AR-15, on the other hand, is the most popular rifle in the United States.
