Barnett introduces yet another breakthrough in crossbow technology with its patented AVI (Anti-Vibration Isolation) system. A system that encapsulates each limb with a special soft-touch material that soaks up shock and vibration to dramatically reduce noise at the shot. AVI also dampens noises that result from incidental contact between the crossbow and trees, stands, arrows or other objects. This package features the powerful Quad 400 crossbow with AVI, the Quad 400's 16" power stroke hurls bolts at up to 345 fps, and it does so quietly with AVI. Package includes the crossbow with 4x32mm scope, quiver and four 22" bolts. Realtree Hardwoods HD camo finish. Draw weight: 150 lbs. Extra bolts are also available so you always have enough for the range or the field. Barnett's Premium Red Dot Scope is simple to use, easy to see and extremely accurate. Compatible with both recurve and Compound Barnett Crossbows. Features 11 dot intensity settings with integrated 3/8" mounts. Manufactures Website Address www.barnettcrossbows.com Warranty Information
