I have one black complete ruger bolt other with exactly 50 rounds on it. It is a take off from ruger mk4 tacticals purchased this year. I replaced it with a VQ bolt. It has a firing pin, extractor, and recoil spring all in place. Just drop in and shoot. I have cleaned the bolt spotless, it looks 100% brand new as you can see in the photos.
