The Bolzen Karabiner-23, or usually shortened to the BK23, was created by Höllenregen in 2035 for use in defense against the larger of the beasts used by the guards stationed at the walls of most of the cities. This was then turned into a 'sniper's rifle.'
The BK23 is a bolt-action rifle with both a special iron sights built for it, and a scope specifically for it. The BK23 also has a folding bipod, and a top hatch for a strip clip, to negate the need to carry multiple magazines.
