Works to adapt almost any traditional or other muzzle loader that has a #11 nipple to use 209 shotgun primers. Made from stainless steel, comes with wrench to install, 1/4-28 thread size. I have one of these on the Pedersoli Hawken that I have listed on GA, they work great! No missfires, hangfires, and I can use Blackhorn 209 powder! These run $20 normally. This is brand new, never opened.
Just a collector trying to thin things out. If you call and I am not there, just leave a message and I'll get back to you. Contact me for more photos. Thanks for looking, Mark
