New 5.56 AK bolt Firing Pin
Older WBP 5.56 bolts used this free-floating firing pin design, until they changed to the spring-loaded design that we receive now. If you have an older WBP free-floating, 5.56 bolt, this is what you need.
If you have a newer spring-loaded bolt, we do have customer reports of using this firing pin with success!

Noice
It didn't fit my pioneer arms at all. But I didn't want to hassle sending it back. Solid little piece regardless.
