The Bowtech BT-X 31 is the perfect combination of speed, balance, and strength in an ultra-compact design. Generating bone- crushing speed at 350 (31? cam system) feet per second. The revolutionary skeletal riser was specifically engineered to remove unwanted weight for optimal balance and reinforced stability. The BT-X features the all-new Micro Sync Dial, giving the shooter the ability to precisely time cam position without sacrificing wasted time in a bow press.
