Knight 26 Inch Aluminum Ramrods are designed for 50 caliber muzzleloaders. The aluminum construction can hold up to the worst abuse in the field. 26 Inch ramrods are designed for 26 inch barrels, and are the standard size. The tough brass tip can take abuse while not scratching the barrel. Threading of 10-32 in the brass tip works with most of the muzzleloader attachments.
