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:
- 3+ Perimeters
- 15% Infill
- 0.15 or 0.2mm Layer Height
- Most parts need supports
- use contrasting colors
Local laws apply
