Get long-range accuracy, guaranteed to 200 yards, with incredible comfort, from the Long Range Hunter Muzzleloader. These .50 and 52. caliber muzzleloader rifles can offer this incredible long-range accuracy and long-term comfort due to their 27" stainless steel, 1:28 twist rate, spiral custom-fluted barrel and special lug system. This makes it more accurate than most black powder rifles because environmental conditions, wear-and-tear to the stock and pressure are not able to shift the barrel out of alignment, a standard feature in match-grade rifles.

Knight Extreme bolt-action inline muzzleloader is one muzzleloader that works on any hunt, in any weather, at any range. The bolt-action design enables you to slip the bolt from the rifle without tools. You can remove your breech plug without having to totally disassemble your muzzleloader if your load becomes fouled or you're ready to clean.
The Knight Extreme's superior dependability comes from the DISCsystem. It uses Full Plastic Jacket technology along with 209 primer. It's easy to load - just press the primer into the fat end of the disc, drop theDISC into the opened bolt, then close the bolt to seal the action. the plastic disc keeps the primer safe from the elements and eliminates misfires, even in rain and snow. We tested this system for reliability, and even after being submerged for an hour the system never failed.
The Knight Extreme bolt-action muzzleloader works like a modern centerfire but is legal for extended black powder rifle seasons. Its synthetic stock and plush recoil pad handle kick back well. The crisp, adjustable trigger breaks cleanly. The fiber optic sights offer an excellent sight picture, but all Knight Rifles are drilled and tapped for easy scope mounting.
The Knight Extreme inline bolt-action disk muzzleloader is Knight's most versatile and dependable muzzleloader yet. Each Knight muzzleloader rifle is designed for superior muzzleloading, and the Extreme is sure to impress anyone who loves black powder rifles.
