Improved the original design where the bolt rotation would get stuck with the ejector, and the extractor is perfectly combined with the bolt.

Note: The extractor may develop a gap after long-term use and fail to extract the shell; simply replace the extractor separately. Additionally, the firing pin compatible with this bolt is in another file on the homepage and needs to be printed for compatibility.

If the ejector force is weak, a small spring can be inserted to achieve perfect shell extraction and ejection.
