MPA is renowned for producing some of the most popular mounts in the Precision Rifle series (PRS). Trusted by top shooters nationwide, our BA mounts have been used to secure optics for multiple PRS, NRL and F-class local and national championship winners. Designed for mounting 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, the interface ensures positive engagement for both in-spec and out-of-spec rail systems. Multiple locking lugs on the bottom of the rail interface guarantee absolute return to zero.
