E3 Enhanced Bolt Features:

• Enlarged Bolt Face – Provides more positive engagement in the chamber and ensures proper seating upon cycling.
• Rounded Bolt Lugs – Less prone to chipping or cracking than traditional square lug designs.
• Reduced-Size Cam Pin – Allows for a thicker bolt web, strengthening a common failure point in the AR-15 bolt design.
• Enhanced Reliability Extractor – Shaped like a “T” this extractor’s pivot point is shifted forward to apply constant pressure on the case rim and reduce extraction failures. Its dual extractor springs provide a failsafe in the event that one fails during hard usage.
