Long Shot Precision, Adjustable Bag Rider (ABR) Universal Rail Mounted

$474.95$629.95 inc. GST

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 (most models). 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, this adjusts the height of the stock without the shooter having to take his or her eyes off the site picture. 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.

Say goodbye to the mound of the expensive and heavy equipment you take to the range. Whether you plan to go to the bench or want to take a shot in the field you are guaranteed to have previously unattainable stability and micro-adjustment with you at all times!


The Universal Rail Mounted ABR (Patent Pending) has been designed to mount directly to the lower picatinny rail with the supplied clamp and bolts. It provides the same functionality as the other ABRs with .910” of travel. Made in the USA from American 6061 Alum and finished with Class II Anodizing they are 12.6oz including the clamp and bolts. The unit is 2.25” tall when closed.

The Universal Rail Mounted ABR top section is the same for all. Only the dowel lengths are different (long front, long rear, or both short) and the dowel material type (standard or hardened).

The bottom section (ELR) is only 0.5″ tall and is made for Protektor branded ELR bags or other bags with very low ears (ABR lower measures 0.850″ wide).   The ELR bottom has a wider base for competitive shooting in which a rear bag is not permitted.
