Maximum Capacity, Minimal Footprint Shepard Arms is thrilled to introduce the "Little Giant Quattro," a custom-built 5.56 AR pistol package designed to deliver overwhelming firepower in an ultra-compact PDW format. The star of this build is the DesertTech Quattro-15 lower receiver, a specialized platform that natively accommodates an incredible 53-round capacity. We paired this multi-cal lower with a CMMG upper and rail set, tying the entire weapon system together with a flawless, premium bronze Cerakote finish.
