The SR-15 E3 Enhanced Bolt features a number of components designed to exceed expectations for durability and service life, even when exposed to extreme and unrelenting conditions. It is a proprietary bolt designed specifically for use in SR-15 and SR-16 rifles. This is a Complete Bolt Assembly with all internal parts installed. The E3 Bolt is compatible with Knight's Armament E3 Barrel Extensions only.

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.
