I have a excellent condition Century C93 5.56mm for trade. The gun has a HK 33 trigger housing. I have had the gun professionally cerakoted in Armor Black. It has a Dead Air Flash hider on it but does come with the OEM muzzle device. The gun comes with 3 Promag 40 round mags, 2 Promag 30 round mags, 1 HK 25 round steel mag and 1 HK 40 round aluminum mag. This is a great gun I am just completely over stocked with 5.56 guns at this point. I would like to make room for some larger caliber guns in the safe. Gun will come with 300 rounds of steel case ammo.
