I hope you will excuse my ignorance, but I just picked up a Whitetail from Doc along with a BH209 breech plug. The plug kit also came with what looks like a striker/firing pin, But for the life of me I can’t figure out how it integrates with the rifle. There is no hole for the bolt handle, and the hole in the back is too small for the spring.
Here is a picture with the original part on the bottom, and the new part included in the kit on the top:
