This is the proprietary bolt for the Knights Armament Corp SR-15 E3 with rounded locking lugs for greatly enhanced service life.

By utilizing modern machining techniques that were not available when the AR-15/M-16 was first designed in the 1960s, the SR-15 E3 system's bolt has much more mass in critical areas, and lasts much longer as a result.  A standard AR-15/M-16 bolt should be replaced at 5000 rounds in critical applications, but the SR-15's service life is many times that thanks to stress relieved, rounded lugs, and a reduced diameter cam pin.  These changes greatly reduce the chances of failure, common to standard AR-15/M-16 bolts

The SR-15 E3 extractor is also greatly improved with revised pivot point, and uses two extractor springs instead of just one. Generous scalloping around the extractor flaw ensures that the extractor will always get a solid grip on the rim, no matter the fouling or grit!

Lastly, the bolt face is fully supported!
