Overview

Built for mounting a scope on a rifle setup, this 34mm, 1.26" mount is intended for shooters who want a purpose-driven interface rather than a generic accessory. It carries a 45 MOA specification and is suited to long-range-oriented configurations where additional elevation adjustment is part of the plan. The design note about possible bolt-handle interference on certain actions is worth considering during installation, especially on rifles with 90 degree bolt rotation. Torque is specified at 6.2 Nm (55 in-lbs) on the scope clamp, and the mount is offered by American Rifle Company in black.

Pros

  • 34mm scope mount size supports compatible optics with a secure mounting system.
  • 45 MOA cant provides built-in elevation adjustment for long-range scope setup.
  • Torque specification is clearly provided: 6.2 Nm, or 55 in-lbs, on the scope clamp.

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 the usual workaround.
  • The scope clamp torque spec is 6.2 Nm (55 in-lbs), so installation should be set carefully rather than tightened by feel.
  • This is a dedicated 34mm mount with a 45 MOA specification, so it is intended for that setup rather than a more universal fit.
  • At $299.00, it sits in a premium price range, which may be a consideration if the rifle does not specifically need this mounting configuration.
