An Assault Bolter is a recent addition to the armoury of the Adeptus Astartes. Many standard centuries of tinkering improvements by Archmagos Dominus Belisarius Cawl has resulted in the creation of the Assault Bolter -- essentially a hand-held pistol version of the conventional Heavy Bolter outfitted with a large box magazine and high-speed autoloader. Although short-ranged, its rate of fire and damage are considerable, with the recoil contained by a mag-shield. These deadly weapons are primarily utilised by Primaris Space Marines Inceptor Squads for deep strikes into enemy lines.
