Browning's straight-pull hunting rifle, engineered for very fast follow-up shots with single-handed cycling. Uses a 7-lug rotary bolt with servo bolt-return, a hand-cocking/decocking system and the Superfeather trigger. Current 4X generation has fluted, threaded barrels and a modular barrel-mounted sighting system. Primarily a European-market driven-hunt rifle (not sold in the US).
