Separating the bolt carrier group’s locking component from the carrier allows for detailed cleaning, inspection for wear or damage, and replacement of parts. This procedure typically involves manipulating specific pins and levers to release the bolt from the carrier. A visual aid, such as a diagram or video, can be helpful for those unfamiliar with the process. An example would be removing the firing pin retaining pin before extracting the firing pin itself.
Regular and proper maintenance is crucial for the safe and reliable operation of any firearm. This process allows one to address potential malfunctions before they occur, ensuring optimal performance and mitigating the risk of failures. Historically, understanding the mechanical workings of firearms has been essential for both armorers and users. This detailed understanding facilitates proper care, repair, and customization.
