The Ballista represents the next generation of fully modular, multi-caliber bolt-action rifles designed to bring surgically precise fire at extended ranges. At the heart of the multi-caliber Ballista is a high-strength, vibration-isolated aluminum alloy receiver with a top mounted MIL-STD 1913 rail plus multiple rail segments for slings, bipod, lasers, lights and other accessories. The Ballista's trigger system is full adjustable for single-stage or two-stage release between 2 and 5 pounds. The 26" fluted barrel may be changed in less than two minutes and each barrel remains true to the receiver's centerline. The Ballista's ambidextrous folding stock is fully adjustable for length-of-pull, buttplate height, comb height, and cast-on and cast-off. The detachable box magazine is fitted with caliber-specific interior assemblies to ensure reliable feeding under all conditions.
