The BOSS™ is a deadly combination of high-octane firepower and agility, hitting targets at a speed of 405 feet per second. The 6-position AR-style buttstock shortens the crossbow's overall length for smaller frame hunters, but extends comfortably to fit a variety of medium to larger shooters as well. The reliability and accuracy that Killer Instinct is known for is achieved through a new Micro-Lite aluminum barrel that eliminates excess weight while still providing precise accuracy. The new adjustable X-Lok front grip and the easy-to-use slim frame create a balanced and compact shooting machine. Rounded off by an integrated Dead Silent Kit for noise reduction, the Boss 405 will certainly deliver deadly results. - Speed: 405fps - Kinetic Energy: 134 ft-lbs - Width: "18.754.75" Tensioned / 18.75" Untensioned - Length": "33.5-36" - Weight: 6.7lbs - draw weight: 220lbs - Power Punch: 13.25"
