An Avenger Mega Bolter is a deadly and formidable rapid-firing weapon utilised exclusively by the Dark Angels Space Marine Chapter elite 2nd Company, known as the Ravenwing, and by the Dark Angels' Unforgiven Successor Chapters. The Avenger Mega Bolter is a smaller version of the Vulcan Mega Bolter. Nose-mounted on the Dark Angels' deadly air corps of Nephilim Jetfighters, they have proven ideal for engaging opposition flyers in deadly dogfights, and can carve through both enemy infantry and vehicle squadrons on ground attack strafing runs.
