Overview

Built for riflemen who want a dedicated mounting solution rather than a generic accessory, this scope mount system is positioned as an evolution of ARC’s earlier M10 rings. It is intended for use on rifles set up with a Picatinny rail and a 34mm scope tube, with a 1.50-inch height and 10 MOA built into the mount. The design note about bolt-handle clearance on some 90-degree actions is worth considering during setup, especially when placing the mount at the far rear of the rail. Torque is specified at 6.2 Nm, or 55 in-lbs, on the scope clamp.

Specifications

Compatibility NoteWhen attached to the far aft recoil slot in the picatinny rail on an action with 90 degree bolt rotation, the 32mm height M-BRACE serrated interface block may interfere with the bolt handle when opened. This issue can usually be avoided by moving the mount forward 1 slot in the picatinny rail.

Pros

  • 34mm scope mount format supports compatible optics and setups.
  • 10 MOA built into the mount for elevation adjustment.
  • Black finish offers a subdued, low-profile appearance.
  • Torque specification is clearly provided for scope clamp installation.
  • Designed as part of ARC's M-BRACE scope mounting system.

Considerations & Trade-offs

  • The 34mm ring size requires a compatible 34mm scope tube, so it is not a universal fit.
  • The 1.50" height is a fixed mounting dimension, which may not suit every rifle, optic, or shooting position.
  • The 10 MOA built-in cant is a deliberate setup choice and may not be ideal for all zero distances or cartridge applications.
  • On actions with 90 degree bolt rotation, placement in the far aft recoil slot can interfere with the bolt handle; moving the mount forward one slot may be necessary.

Frequently Asked Questions

What tube size is this scope mount made for?

This product is listed as a 34mm scope mount.

What height and cant does this mount have?

The title lists it as a 1.50" mount with 10 MOA.

Is this a one-piece mount or separate rings?

The source describes it as the M-BRACE Scope Mounting System, but it does not explicitly state whether it is a one-piece mount or separate rings.

What torque should be used on the scope clamp?

The listed torque spec is 6.2 Nm, or 55 in-lbs, on the scope clamp.

Will it fit every rifle without clearance concerns?

Not necessarily. The source notes that on actions with 90 degree bolt rotation, the 32mm height M-BRACE serrated interface block may interfere with the bolt handle when opened if mounted in the far aft recoil slot. Moving the mount forward one slot may avoid that issue.
