First introduced in the US in the spring of 2014, the Tavor SAR won immediate acclaim and achieved record sales as the first bullpup centerfire rifle to win large acceptance in the US market, due largely in part to its pedigree as the battle proven carbine of the Israel Defense Forces (IDF). This is the toughest, most compact, most reliable semi-auto centerfire rifle you can own. The Tavor SAR Flattop incorporates a full-length Picatinny style top rail in addition to the standard short rail mounted at a 45 degree angle opposite the charging handle.
