Browning A-Bolt
The A-Bolt Rifle is a bolt-action rifle designed by the American Browning Arms Company. It is manufactured by Miroku Corp in Japan. The A-Bolt replaced the Browning BBR in 1984. It is a popular hunting rifle due to its accuracy and availability. Description The A-Bolt rifle is a bolt-action rifle with a short-lift bolt angle of 60 degrees. It uses a non-rotating bolt sleeve (partial sleeve on first generation A-bolt rifles). When the bolt is unlocked, smoothness is achieved with three guide ribs aligned with three locking lugs, enabling precise movement (only on the second and third generation A-bolt rifles). These three locking lugs also greatly increase bolt strength. The bolt's smoothness is also increased with a unique cartridge depressor; the cartridge depressor stays in place independent of the bolt's position.

AR-15
An AR-15-style rifle is any lightweight semi-automatic rifle based on the Colt AR-15 design. The original ArmaLite AR-15 is a scaled-down derivative of Eugene Stoner's ArmaLite AR-10 design. The then Fairchild Engine and Airplane Corporation division ArmaLite sold the patent and trademarks to Colt's Manufacturing Company in 1959. After most of Colt's patents for the Colt AR-15 expired in 1977, many firearm manufacturers began to produce copies of the Colt AR-15 under various names. While the patents are expired, Colt retained the trademark of the AR-15 and is the sole manufacturer able to label their firearms as ''AR-15''. The "AR" in Colt AR-15 stands for "ArmaLite Rifle", not " assault rifle". The Federal Assault Weapons Ban restricted the sale of the Colt AR-15 and some derivatives in the United States from 1994 to 2004, although it did not affect rifles with fewer listed features. After the term modern sporting rifles was coined in 2009 by the US National Shooting Sports F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
