We started by increasing the one-piece MonoBlock barrel length to 26" to ensure magnum long-range performance, capable of handling Pyrodex Pellet charges up to 150 grains. Next we added 6 precision machined flutes for weight reduction and increased barrel stability. A bullet-guiding muzzle completes the barrel design and is available in your choice of matte blue or nickel in either .45 or .50 caliber. Barrel is also drilled and tapped for easy scope installation. And we didn't stop with the barrel! the new FireBolt™ 209 UltraMag also features a recoil reducing resin filled stock and a vented recoil pad, a must when shooting long range magnum loads. We complete the ultimate muzzleloader by lowering the trigger pull to a smooth 3 1/2 lbs. and added a quick release stainless steel bolt. FireBolt™ 209 UltraMag rifles come standard with #209 primer ignition, the hottest system available providing 10 times more fire than a standard #11. IllumiNATOr fiber optic sights, ventilated recoil pad, sling swivel studs, and stainless steel bolt assembly all round off this perfectly balanced rifle.
