Flat Mount ABR

The Flat Mount ABR (Patent Pending) is a direct bolt on to the MPA BA and Hybrid models and is supplied with the proper length bolts. The two step aluminum cross stud for the monopod (called the Bag Rider Barrel) will be used for the front mounting bolt. The ‘Bag Selection’ page goes over the lower rider differences. This ABR provides the same functionality as the other ABRs. Patent Pending & Made in the USA from American 6061 Alum and finished with Class II Anodizing they are less than 14oz.

ORYX Chassis – 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 bolted onto the lower stock without adding a picatinny rail. Since machining is required either way to add the bolt holes the MPA designed ABR has two small slots and counter bored areas for the bolt heads to be recessed. See pic to left of ORYX chassis with MPA ABR

Caliber restrictions:
.338 and smaller calibers can use the Standard dowels
.33XC and larger needs the Hardened dowels

Do NOT lower the rider past the dowels being level with the top of the ABR.

Please note that this product does not fit all MPA stocks.
