This MasterPiece Arms mount is designed to mount performance optics onto bolt action rifles with picatinny rails. The 34mm one-piece configuration accommodates 34mm tube optics with a 1.250″ center height and 0 MOA configuration. The mount is precision machined from 6061 T6 aluminum and finished in hard coat T3 Mil-Spec anodize.
The interface ensures positive engagement for both in spec and out of spec rail systems, and Absolute Return to Zero is possible through multiple locking lugs located on the bottom of the rail interface. This mounting system is designed to handle large objectives up to 56mm. Horizontal split rings provide secure optic mounting and repeatable positioning.
The 1.250″ height specification accommodates optics with erector housing to main tube measurements of 0.330″ or shorter. As part of MasterPiece Arms’ BA Series, this mount is engineered for precision rifle applications and delivers the uncompromising quality expected by serious long-range shooters.
