From Warhammer 40k - Lexicanum
(Redirected from Arbitrator (combi-bolter))
The Arbitrator was a heavily customized Combi-bolter that was one of the Primarch Roboute Guilliman's favoured side arms when in open battle. It was given its name by Guilliman for the matters it settled and was tooled to tolerances beyond any but the Archmagos of the Mechanicum could fathom, though he was still able to wield it as deftly as one of his Legionaries might handle a pistol. Of note was the weapon's bolt shells were hand-crafted by the finest ordnancer-wrights of the Legion's forges and were fitted with micro-atomantic compression warheads.
