TenPoint Viper S400 Crossbow Package

  • TenPoint's shortest forward-draw crossbow ever produced, the light-weight Viper S400 measures just 32-inches in length yet delivers speeds up to 400 FPS
  • Featuring the NEW revolutionary ACUslide Silent Cocking and Safe De-cocking System 
  • ACUslide Cocking and De-Cocking System provides silent cocking and safe, controlled de-cocking. Forget holding buttons, using straps, and losing control while de-cocking. Simply backwind the handle – stopping at any point without fear of damage, injury, or losing control 
  • S1 Trigger sets a new standard in high performance crossbow accuracy with a 2-stage, zero-creep design featuring a roller sear system that delivers a crisp, 3.5-pound pull. Its stainless steel latch locks the trigger box at full-draw – relieving the tension from the ACUslide unit and guaranteeing that your trigger box is in the same location on each shot, leading to 48% increased down-range accuracy
  • Micro-Trac Barrel reduces string-to-rail contact by an incredible 50% - leading to increased accuracy and the longest string life in the industry, while Tec-X Stock dramatically minimizes stock size, reducing the weight of the crossbow by 1/2-pound
