Overview

Built for mounting a 34mm scope on a Picatinny rail, this scope mount is aimed at riflemen who want a purpose-built setup rather than a generic accessory. It carries forward the M-BRACE system from American Rifle Company’s earlier M10 rings, and the included torque spec for the scope clamp is 6.2 Nm (55 in-lbs). The product note is worth considering during setup: on some actions with 90 degree bolt rotation, the rearward slot position may interfere with the bolt handle, though moving the mount forward one slot can usually avoid that. Finished in black, it suits hunters and shooters setting up a rifle for deliberate, repeatable optic mounting.

Considerations & Trade-offs

  • The 32mm height serrated interface block may interfere with the bolt handle on some actions with 90 degree bolt rotation when mounted in the far aft recoil slot; moving the mount forward one slot is noted as a common workaround.
  • This is a dedicated 34mm mount, so it is only appropriate for optics with a 34mm tube.
  • The mount is specified with a 60 MOA cant, which is a deliberate setup choice rather than a general-purpose option.
  • Scope clamp torque is specified at 6.2 Nm (55 in-lbs), so installation should be done carefully to stay within the stated spec.
