Masterpiece Arms’ BA Series Mounts are engineered for securing high-performance optics to bolt action rifles equipped with Picatinny rail scope bases. Precision machined from 6061 T6 aluminum and finished in hard coat T3 Mil-Spec anodize with horizontal split rings, each mount features multiple locking lugs on the bottom of the rail interface that deliver Absolute Return to Zero capability. The interface design ensures positive engagement with both in-spec and out-of-spec rail systems.
This 30mm mount accommodates large objectives up to 50mm and stands 1.125 inches high, with an erector housing to main tube measurement of 0.210″ or shorter. Four mounting locations positioned on the left and right sides in both front and back configurations feature holes spaced at 20mm intervals for compatibility with other Unimount accessories. Bore size consistency is held within +/- .0002″, and roundness and cylindricity are maintained within .0002″, enabling confident optic and mount transfers between multiple rifles using only windage and elevation adjustments.
The mount measures 4.760″ in length and weighs 6.8 oz. A superior clamping surface maximizes rail engagement and positively locks your optic in place. Every Masterpiece Arms mount is backed by a lifetime warranty.
