Airfoil competition upgrade

Add this to the cart with your empty Airfoil or Airfoil lowboy for the competition upgrade.  This upgrade gets your bag filled with a new media I discovered that is grittier than pool sand for fantastic stability, the rear of the bag sealed shut, and a 1/2" rubber base pad added to the bottom of the bag. 

This gives you a couple advantages over the normal Airfoil, first it makes the base more rigid and allows you more vertical adjustment without bowing the whole bag.  This is great when you are in a pinch for time in a match and need a little extra elevation, but don't have time to make changes to your bipod.  The rubber base also grabs the surface you are shooting from, which really helps it stay put under recoil.  

I have figured out a way to attach the base on the outside to the rubber base inside the bag, making it extremely rigid and solid, This upgrade adds about 1.2 pounds to the overall bag.  

Please don't purchase this unless you are buying an Airfoil or plan to return an Airfoil for the upgrade.
