Fosbery's Pump Shotgun: An AR15 Bolt in 1891
This review delves into Colonel George Fosbery's 1891 pump-action shotgun prototype, a rare piece featuring a sophisticated 6-lug rotating bolt. Despite its advanced design, predating AR-15 bolt technology by decades, it saw no commercial success due to British sportsmen's preference for break-action designs. The example examined was a modified rifle, highlighting Fosbery's innovative, albeit commercially unsuccessful, approach to firearm mechanics.
