The lightweight Air Brakes are constructed of an ultra-modern energy absorbing compound and will reduce recoil energy and noise on any Matrix or Micro model crossbow.Tests show an eight-decibel reduction in noise without reduction in arrow speed.  The kit comes complete with bars, pads and mounting hardware, installation takes only minutes. 

NOTE: The string does need to be removed to install this kit so we advise you also purchase an Excalibur stringing aid.
