The Angle Mounted Adjustable Bag Rider (Patented) is designed to bolt directly to the bottom of the MDT stocks (and some Savage) that have an Angled mounting surface. There must be a mounting SLOT in the bottom. Made in the USA!

Two lower rider options are available - the V and ELR. The ELR base is .850” wide. The ‘Bag Selection’ page goes over the lower rider differences. The ABR™ provides rock solid stability, straight tracking and vertical adjustment. The ABRs are CNC machined from USA made 6061 Alum, Anodized Class II Black and weighs 12-14 oz . 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 to install the supplied bolts. The ABR™ provides about .95” of travel for the short dowel and 1.48” for the long dowel. Older models stocks ‘without the slot’ will need machining to add the 1/4” bolts through the stock.

• A new ‘Quick adjustment’ thread option (Coarse thread) is available for PRS, Hunting - use requires Hardened Dowels

If you do not see your rear stock listed below there are Two pics that show the measurements needed to verify if the stock will accept the long dowels. If you are unsure please use the contact button and send picture of the rear stock.

The Flat mount ABR™ (Patented) will directly bolt on to the MPA BA Comp, Hybrid, ESR and Bergara Premier Competition with an MPA Chassis models and it is supplied with the proper length bolts (short dowels). The two step aluminum cross stud (called the Bag Rider Barrel) will be used and the ‘longer’ front mounting bolt - it will go up into the front slot of the ABR. The shorter bolt goes up into the rear slot. While ABR™ is opened start the two supplied bolts with your fingers - finish tightening with an Allen wrench. DO NOT take apart the ABR. There is a short 1/4-20 bolt installed in the ABR that has to be removed for applications other than the MPA chassis.

• A new ‘Quick adjustment’ thread option (Coarse thread) is available for PRS, Hunting - use requires Hardened Dowels

Caliber restrictions for dowels:

• .338 and smaller will use the Standard dowels

• .33XC and larger will need the Hardened Dowels

• PRS use requires Hardened Dowels

Direct Bolt On application:

MPA BA: Competition, Hybrid, ESR, Evolution, Lite, and Bergara Premier - Short Dowels (The Long dowels will require milling)

MPA Ultra Lite Chassis - Long Dowels (No mods needed)

MPA Hunter - Longer dowels (No mods needed)

MPA BA PMR - Longer dowels (No mods needed)

Modifications Required:

MPA BA: Competition, Hybrid, ESR, Evolution, Lite, Ultra Lite, and Bergara Premier-to fit the Longer dowels the rear dowel will have to pass into (not thru) the stock so milling a pocket is required (See pic with BLACK stock) or see the Installs page

ORYX Chassis -(Long Dowels) If your chassis does not have the slot for the M-Lok - we suggest to reduce height added to the rear stock- that you directly bolt onto the lower stock without adding a picatinny rail. Since machining to your stock is required either way to add the bolt holes (for a Rail or ABR direct mount) the Flat Mount ABR has two small slots and counter bored areas for the bolt heads to be recessed. See pic to left of ORYX chassis with Flat Mount ABR. If you do have a M-lok slot the Rail Mounted ABR‍ ‍is what you need.

XYLO chassis - (Short Dowels) The lower rider (part of the stock) will need to have 2 bolt holes added to mount the Flat Mount ABR (which already has 2 small counterbored slots).

Sig Cross- The rear stock must be modified to fit the ABR and the holes milled in the ABR to clear 10/24 bolts. Please contact us for details. The LOP plate must be modified to clear rear dowel. See pic and ‘Installs’ page

MPA Matrix - Custom installation (milling required) see picture and ‘Installs’ page
