Features a built-in cleaning jag which conceals a ball puller. Remove the ball puller and that end is threaded 8x32. The other end has a 10x32 thread tip installed on it. All Super-Rod ends are pinned to the shaft. Made from a non-abrasive material, these rods can be used without a rod guide and will not wear the muzzle of the rifle. All rods are 3/8" diameter, except the ones marked by an @ which are 23/64" diameter. Great for under barrel replacements. Note: When pulling a ball, center two 2 1/2" cleaning patches on the screw. This will help keep the screw centered in the barrel, and not slip off when contacting the ball. Don's see the rod you need listed? We will custome make any rod you want. Just give us length and diameter, we will do the rest. Please add 5.00.
