MasterPiece Arms offers a repeatable and precise platform for adjoining precision optics to rifles topped with Picatinny rail via its BA Series Mounts. The MPA mounting system is built to tolerances down to 0.0002" and is available for optics with main tube diameters of 1", 30 mm, 34 mm, 35 mm and 36 mm, with the option to include 20 m.o.a. of built-in elevation for ranges that exceed an optic’s ability for adjustment. Mounts feature a hard-coat anodizing process to the 6061-T6 aluminum material used, rendering a satin-black finish. The 3.5" mounting footprint incorporates additional locking lugs to aid mounting consistency and return-to-zero when removal and re-installation is necessary. The platform retails for $250, and additional options for optic heights are available. For more information, check out masterpiecearms.com.
