The John Rigby & Co Rising Bite Double Rifle in 577 Nitro Express is among the most powerful and most unusual of all Rigby's rifle commissions. The Rising Bite action's superior locking geometry is well-suited to the extreme pressures generated by the 577 NE, and Rigby produced a small number of these guns for clients who demanded maximum stopping power. These guns weigh approximately 16 pounds and generate recoil comparable to a light artillery piece. Type: Rifle Action: Double / SxS Caliber: 577 Nitro Express Capacity: 2 Year introduced: 1900, United Kingdom Weight: 244 oz Overall length: 44.5" Status: Active Intended use: Dangerous Game
