The Adjustable Bag Rider (ABR) is made and assembled in the USA. Made out of the highest quality American aluminum, CNC made and anodized for superior wear resistance, the ABR is made to last and weighs less than a pound. The custom dowels come in either hardened alloy steel or Stainless Steel and ride in linear bearings for consistent smooth operation. A custom-designed SS thumb wheel rides in two Delrin thrust washers that are known for their strength and creep resistance. The ABR replaces the need for expensive, heavy, and bulky adjustable front rests and wobbly monopods. Installation is simple, quick, and you never need to remove it.
