AR15 Cut Away Bolt Carrier Assembly

Cut Away Model of an AR15 Bolt Carrier Assembly scaled to 200% for demonstration and education purposes.

I made the ejector longer than usual. This way you can trim it to length to accommodate different lengths of springs you might have around. For example, I used the spring from a ballpoint pen for the 200% scale model.

Recommended Print Settings:
