It's a bolt for Savage B.MAG rifle in 17 Winchester Super Magnum caliber. The bolt you have was recalled due to the bolt cover (the piece at the back end) could accidently contact and move the safety button when the handle was moved to cycle the action. The links below are to Savage's website showing the rifle and an article on the bolt recall. I'm putting the links here because the opinion won't submit with them in the other block. https://www.savagearms.com/content?p=firearms&a=product_summary&s=96901 https://www.americanrifleman.org/articles/2015/8/24/savage-arms-recall-notice-on-bmag-rifle-bolts-17-wsm#:~:text=Savage%20Arms%20has%20issued%20a,into%20the%20%E2%80%9Cfire%E2%80%9D%20position.&text=The%20kit%20includes%20simple%2C%20step,the%20bolt%20handle%20and%20cap.
