NOTE: These are refurbished and commercially packaged bolts direct from Knight's Armament Company
The KAC SR-16 E3 Bolt is compatible with Knight's Armament E3 Barrel Extensions only, not for use in AR15/M4 pattern firearms with standard, M16/M4 barrel extensions.
Finished in hard chrome, this is a must have for any SR-16 owner to secure a back-up bolt in the unlikely event of a critical parts failure.
- 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 fail safe in the event that one fails during hard usage.
This is a Complete Bolt Assembly with all internal parts installed.
