Knights Armament SR-15 E3.2 Bolt Assembly
The SR-15 E3.2 Enhanced Bolt Assembly is the next generation in Knights Armament SR-15 improvements. The E3.2 Bolt Assembly is finished in hard chrome and features dual ejectors for extended service life even under the most demanding conditions.
The chrome finish and dual ejectors are especially helpful when shooting the host weapon system suppressed. When shooting suppressed there is increased blowback in the weapon system. The harm chrome on the bolt allows the weapon to run longer and more reliably over the standard E3 bolt, while, the dual ejectors increase reliability of ejection.
E3.2 Enhanced Bolt Features
- Dual Ejectors: Provides more positive ejection for increased reliability with suppressors.
- 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.
The E3.2 bolt is only compatible with SR-15s and KAC E3 barrel extensions and WILL NOT WORK with standard AR-15/M4 barrel extensions.
