MasterPiece Arms manufactures the BA Series Bolt Action Mount, a 34mm scope ring system built for rifles equipped with Picatinny rail scope bases. Standing 1.125″ in height with 0 MOA, this mount combines precision machining from 6061 T6 aluminum with hard coat T3 Mil-Spec anodize finishing to resist corrosion and withstand demanding field use.
The BA mount uses horizontal split rings that maintain positive engagement with both in-spec and out-of-spec rail systems. Absolute Return to Zero capability comes from multiple locking lugs positioned on the bottom of the rail interface. The design accommodates objectives up to 56mm and provides over 3.5 inches of rail interface for solid lockup onto your rifle’s scope base. Four accessory mounting locations on each side feature holes spaced at 20mm intervals for compatibility with other Unimount accessories.
This mount works well for shooters who move their optic between multiple rifles—windage and elevation adjustments allow confident transfers across different platforms. The 1.125″ height suits optics with an erector housing to main tube measurement of 0.210″ or shorter, keeping scope clearance and field of view optimal without excessive height above the receiver.
