MPA's BA mounts are among the most popular in the Precision Rifle series (PRS), trusted by top shooters across the country. These mounts have helped secure victories in multiple PRS, NRL and F-class local and national championship matches. Designed for high-performance optics on bolt action rifles with picatinny rail scope bases, the BA series mounts are precision machined from 6061-T6 aluminum and finished with Mil-Spec anodizing. Featuring horizontal split rings, they ensure positive engagement with both in-spec and out-of-spec rail systems. With multiple locking lugs on the bottom of the rail interface, they provide absolute return to zero.
