The LaRue Tactical LT111 OBR QD Scope Mount is a precision-engineered 34mm mounting interface designed for MIL-STD-1913 Picatinny rails. Built without a forward cantilever, it positions the optic rings directly over the base for balanced weight distribution on continuous top rails and bolt-action rifle chassis. It incorporates dual tool-adjustable Quick-Disconnect (QD) locking levers that enable rapid, repeatable optic attachment and detachment with return-to-zero capability.

Key Features:

• 0 MOA Base: Provides zero built-in elevation, engineered specifically to align optics on rifle receivers and chassis that already feature integral cant (such as 20 MOA rails).
• Clip-On Device Alignment: Sets the optical centerline at 1.535 inches (approx. 39 mm) above the rail, maintaining in-line optical axis alignment with clip-on night vision (CNVD) and thermal units.
• Wide Ring Spacing: Features 2.9 inches of clearance between ring faces to accommodate wide central saddle sections and oversized turret housings (such as U.S. Optics T-Pal bodies).
• Precision CNC Machining: Machined from aircraft-grade aluminium with a matte black hardcoat anodised finish for extreme durability against heavy-calibre recoil.

• Weight: 8.0 oz (approx. 227 g)

Who is the LaRue Tactical OBR QD Scope Mount (34mm) for?

• Precision Rifle Competitors — Requires a 0 MOA 34mm QD scope mount that fits receivers with pre-existing cant while maintaining a 2.9-inch ring spacing to clear oversized target turret assemblies.
• Tactical Marksmen — Relies on a 1.535-inch centerline height in a 34mm mount to ensure straight-line optical alignment with forward-mounted clip-on thermal or night vision devices.
• Long-Range Chassis Shooters — Needs an 8.0 oz non-cantilever 34mm QD scope mount that centers heavy precision optics directly over continuous Picatinny rails without forward offset.

Less suitable for: Optics with 30 mm, 1-inch, or 35 mm main tubes (which require dedicated-diameter mounts), non-monolithic AR-15 receivers requiring forward eye-relief offset (which require a cantilever mount), bolt rifles seeking a low-profile optic setup below 1.535 inches (which suit a lower 1.285-inch mount), or rifles utilizing direct-action receiver screw patterns without a MIL-STD-1913 Picatinny rail base.
