The Adjustable Bag Rider (ABR) is made locally 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 washer 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. It is the only bolt-on enhancement that provides vertical adjustment while providing horizontal stability without requiring positional body changes. Installation is simple, quick, and you never need to remove it.

The two lower riders (SQR bottom or V bottom) are designed to provide optimal performance when used with a rear bag with ears. No need for positional changes to the rifle and body which cause point of impact inconsistencies. Say goodbye to the mound of 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 ABR is designed to work with a rear bag and any bag or sand sock can be used - but a bag with ears works best. Bags with bunny ears allow full access to the thumb wheel at all times. If a heavy leather bag is used and there is space in between the ears and the rider the groups will be horizontal. If there is a space, remove the ABR from the bag and, pushing down with your thumb on the top of the ears to shrink the space between the ears. if all space cannot be removed a shim can be tested. For example, lay a piece of leather across the top of the ears and push the ABR down on top of it. 

Long Shot Precision (LSP) has worked closely with the Protecktor Model company to develop the "round back" rear shooting bags. These bags have been collaboratively designed for use with the ABR to maximize clearance from the thumb wheel to the front of the bag ear. We recommend you call Protektor Model and let them know which ABR you've purchased and the height you need and they will guide you to the best Round Back Bag. 


**Do NOT lower the rider past the dowels being level with the top of the ABR. Please note that this product does NOT fit the Ruger Precision Rimfire Rifles without some modification.

**Please allow a week before shipping in some cases.
