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

$519.95$569.95 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!


Rail Mounted Adjustable Bag Rider (Patented) designed to clamp to a lower picatinny rail. It provides the same superior functionality as the other ABRs. It ships with the Rail Clamp and 10-32 bolts (torque to 18 inch pounds 5/32” allen wrench). The ABR has about .95” of travel with the short dowel and 1.48” for the long dowel. See list below for a list of popular rifle stock/chassis that this ABR will fit and which dowel length to purchase. As more rifles or rear stocks are identified as a direct bolt on application the list will be updated.

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

The bottom section is available in three variants: V Bottom, Square Bottom, ELR

The V bottom base is designed to fit the standard 3/8” stitch bag (2 stitch) you may already have (ABR lower measures 0.375″ at the lowest/thinnest point). The Square Round Bottom ABR is designed to fit a bag you may have if you already purchased one for your standard stock/chassis (ABR lower measures 0.850″ wide). ELR Bottom is the same as the Square bottom model but 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).  Functionality and construction are the same but the difference resides in how the shooter chooses to use it. The Square/ELR bottom has a wider base for competitive shooting in which a rear bag is not permitted.
