  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™ (.338 Lapua Mag., .300 Win. Mag. and .308 Win.) 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.
