That was right after they did the hostile takeover of Professional Ordnance/Carbon 15 out of Arizona.
The Professional Ordnance bolt and extension had the radial lugs, no right angles in the cross section.

Looks like a KAC E3 bolt.

Obviously we all know the E3 design to be a nearly-bombproof design, so what makes KAC lug design different from the one you posted (Professional Ordnance)? |

KAC KNOWS HOW to properly heat treat bolts. The old Professional Ordinance bolts are notorious for failing. |

KAC KNOWS HOW to properly heat treat bolts. The old Professional Ordinance bolts are notorious for failing. So with similar designs, just the heat treating is enough to make or break (literally) a bolt to that extent? I'm not familiar with Professional Ordnance, so I have no clue as to their history. Only KAC.
