The Ultimate Lightweight Precision & General-Purpose Rifle
Shepard Arms is proud to present this uncompromising 16" precision build, designed to bridge the gap between rapid close-quarters engagements and long-range precision marksman work. Built around a fully ambidextrous American Defense Mfg (ADM) receiver set and a match-grade 16" Proof Research Carbon Fiber barrel, this rifle combines extreme weight reduction with match-grade accuracy and zero thermal drift.
Finished in a custom Carbon Gray Cerakote, this turnkey system is completely fitted out with premium glass, offset red dot, suppressor-optimized gas management, and a dedicated Griffin Armament ultra-lightweight suppressor package.
