Browning BAR, Mark III, Semi-automatic, 270 Winchester, 22 Barrel, Blued Finish, Walnut Stock, 4 Rounds 031047224 The Browning BAR has a long standing tradition for achieving bolt action like accuracy in an autoloading rifle. Some of this is accounted for in the extreme level of precision and careful craftsmanship that goes into every rifle. But the design really sets it apart. The gas system combined with a 7-lug rotary bolt provide significant recoil reduction for comfort, while at the same time locking in bolt action-like accuracy.
