Overview

Built for mounting a 30mm scope on a Picatinny rail, this scope mount is aimed at riflemen who want a purpose-driven setup rather than a generic accessory. It carries a 10 MOA cant and a 1.50-inch height, making it suited to precision-oriented rifles where optic positioning matters. The design is presented as part of American Rifle Company’s M-BRACE system, with a stated scope clamp torque spec of 6.2 Nm (55 in-lbs). One practical note: on some actions with 90 degree bolt rotation, the rearward placement of the 32mm height interface block may interfere with bolt handle clearance, so mount position should be checked carefully.

Pros

  • 30mm scope mount with 1.50-inch height and 10 MOA built in
  • Part of the M-BRACE Scope Mounting System from American Rifle Company
  • Designed as an evolution of ARC’s proven M10 Scope Rings

Considerations & Trade-offs

  • The 32mm height M-BRACE serrated interface block may interfere with the bolt handle on actions with 90 degree bolt rotation if mounted in the far aft recoil slot; moving the mount forward one slot is noted as the usual workaround.
  • This is a 30mm scope mount with a 1.50" height and 10 MOA built in, so it is intended for setups that specifically call for those dimensions rather than a more universal fit.
  • The scope clamp torque spec is 6.2 Nm (55 in-lbs), so installation calls for attention to the specified setting rather than hand-tightening by feel.
  • The product is presented as part of a mounting system, so buyers should confirm compatibility with their rifle, rail position, and optic before ordering.
