We have many standard lengths to fit most guns. The 3/8" diameter, 31 1/2 to 33" long with 10-32 or 8-32 thread on the threaded end. Made of hickory with cleaning jab end is made from solid brass and is secured with pins. The jag is cupped for sabots which allows you to load without changing the tip. The opposite end can be used to add a t-handle or ball handle or any jag you need. This ramrod makes a good under the barrel replacement rod as well.
For a rod length refer to the ramrod reference page above (ramrods). If you don't see your gun in the list measure your current rod and choose that length.
