L7Q3

Behold the laundry list of enhancements our design brings to the table:

Carrier:

  • Altered cam path for longer dwell time and more robust extraction
  • Modified gas hole improves gas flow across the bolt’s tail
  • Additional gas ports on right side and modified orientation to improve gas flowing through the ejection port, and not into your face
  • Relief grooves added to the top and bottom to channel debris and maintain fluid movement

Bolt:
