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 Angle Mounted Adjustable Bag Rider (Patented) is designed to bolt directly to the bottom of the MDT stocks (and some Savage rifles which have an MDT made chassis) with the supplied bolts. You must have an M-LOK Slot in the bottom of your buttstock for these to fit (older models without the M-LOK slot have two holes and will need machining to mount the 1/4” bolts)
There are four mounting holes providing the options to cover stock variations – select the two mounting holes farthest from each other. A 5/32 hex wrench will be needed. The ABR has about .95” of travel for the short dowel and 1.48” for the long dowel.
If you do not see your rear stock listed below there are two photos that show the measurements needed to verify if the stock will accept the long dowels. If you are unsure please contact Long Shot Precision and send a picture of the rear stock.
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 two variants: V Bottom, or 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). ELR Bottom is designed to fit a bag you may have if you already purchased one for your chassis and is 0.5″ tall, they are 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 ELR bottom has a wider base for competitive shooting in which a rear bag is not permitted.
Direct Bolt on Applications and the Dowel Length version which will fit it.
ACC and ESS (SRS-X and SRS-X Elite) – Non-folding – Long Dowels
ACC and ESS (SRS-X and SRS-X Elite) – Folding stock- Short Dowels
SRS V5 – Skeleton Rifle Stock – Short Dowels
SCS-Lite – Long Dowels (The shorter tube length may require the Folding Stock Adapter to increase LOP- or a longer tube)
SCS – Long Dowels (The shorter tube length may require the Folding Stock Adapter to increase LOP- or a longer tube)
Savage B22 & B17 – Short Dowels – Minor modifications are necessary as M-LOK nuts and bolts will be required and the counter sinking of the heads on the bottom of the ABR will be required for a flush mount. (See Picture)
Hardened or Standard Dowels:
.338 and smaller calibers will use the Standard Dowels
.33XC and larger needs the Hardened Dowels
NOTES: Do NOT lower the rider past the dowels being level with the top of the ABR. MDT Rear buttstock weight will need to be modified to clear the bolt heads – a dremel can be used (see pic). Please note that this product does not fit anything other than the MDT / Savage with an M-LOK MOUNTING SLOT.
