Overview

Built for mounting a 34mm scope on a rifle with a 20 MOA setup, this scope mount is aimed at hunters and riflemen who want a purpose-driven interface rather than a general-purpose accessory. It carries forward the design approach of American Rifle Company’s M10 rings and is presented as part of the M-BRACE mounting system. The listed torque spec for the scope clamp is 6.2 Nm (55 in-lbs), and the product note should be considered during installation on actions with 90 degree bolt rotation, where placement may affect bolt-handle clearance.

Pros

  • 34mm scope mount with 1.50-inch height and 20 MOA cant
  • Black finish for a low-profile, subdued appearance
  • Designed as part of ARC's M-BRACE Scope Mounting System
  • Torque specification provided: 6.2 Nm, or 55 in-lbs, on scope clamp
  • Compatible mounting note included for Picatinny rail placement considerations

Considerations & Trade-offs

  • The 1.50" height and 20 MOA cant are fixed configuration choices, so fit and optic setup need to match the rifle and intended zero distance.
  • The mount is specified for 34mm scopes, which limits use to optics with that tube diameter.
  • A note in the product data warns that the 32mm height M-BRACE serrated interface block can 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 may be necessary.
  • Scope clamp torque is specified at 6.2 Nm (55 in-lbs), so installation should be done carefully to stay within the stated spec.
