Durasteel Assault Rifle
Durasteel Assault Rifle is the Novakid tier 4 craftable unique two handed gun. It's made using durasteel bars at a replicator. The one handed tier 4 Novakid gun is Durasteel Revolver, which is less powerful.
This weapon is notable for its very high rate of fire - almost no procedurally generated rifles will fire this rapidly. Despite this, it is very energy efficient and has a consistent, reliable firing pattern; it remains useful until endgame. In fact, the design is so extremely reliable that procedurally generated assault rifles that closely mimic its firing pattern will be more powerful overall than other rifle designs.
