The first of two Hammered Grey SMGs. One "economy" version with 18 round clip and no accessories, and another with a 35 drum and weapon sling. Both have the same performance upgrades.
12.6v, restrictor removed, padded, 6kg OMW spring. With the short barrel it's hitting up to 65ft.
I couldn't think of a name and will likely change it; it has a hammered finish and shoots hard - for now it's 'The Hammer' v1.
