A Custodian Guardian Spear with built-in Bolt Caster
A Bolt Caster is a double-barelled Bolter used as the primary ranged weapon of the Adeptus Custodes. The Bolt Caster is usually built into the primary weapon used by the Custodians, often a Guardian Spear or Sentinel Blade.
In the skilled hands of a Custodian, a Bolt Caster is able to lay down a hail of fire at short range that cuts down the foes of the Emperor with ease.
