Spuhr ISMS QDP-5002 Ø35mm Tube 0 MIL (38 mm High) Quick Detach Picatinny Scope Mount

• 0 MIL/0 MOA Height: 38 mm/1.5”
• Length: 126 mm/4.96” (mount body only)
• Weight: 277 g/9.8 oz
• 10-degree wedge included

• Monolithic one‑piece construction - CNC‑machined from a single billet of aerospace‑grade aluminium to eliminate tolerance stacking, flex, and ring misalignment common in multi‑piece mounts.

• High‑rigidity structural geometry - Optimised cross‑section and material distribution provide exceptional torsional and vertical stiffness, maintaining optic alignment under heavy recoil and dynamic loading.

• Hard‑anodised surface treatment - Type III hard anodising delivers excellent abrasion resistance, corrosion protection, and a non‑reflective tactical finish.

• Diagonal ring split design - Improves load distribution around the scope tube while keeping elevation and windage turrets fully accessible, preventing obstruction during adjustment.

• Integrated scope levelling system - Built‑in bubble level allows the shooter to reference rifle cant and optic alignment directly on the mount for precise long‑range shooting.

• Multi‑axis accessory interface -  Machined mounting points on multiple faces of the mount support direct attachment of optical and electronic accessories without adding separate rails.

• Low‑profile accessory mounting - Keeps mounted devices close to the bore axis and centre of mass, preserving rifle balance and minimising parallax and offset errors.

• Precision‑cut recoil lugs and rail interface - Provides repeatable, slip‑free engagement with Picatinny rails for consistent return‑to‑zero performance.

• High‑strength fastener system - Torque‑optimised fasteners maintain clamping force under vibration and recoil, preventing optic movement or zero shift.

• Designed for extreme‑range precision - Engineered to support the mechanical and optical demands of ELR, PRS, and professional long‑range shooting platforms.

Why is a 0 MOA base used with 35 mm optics?
Most 35 mm scopes already have large elevation ranges, so keeping the mount flat allows the scope’s internal system to remain centered for optimal tracking accuracy.

How does the QDP system maintain zero with heavier optics?
The dual cam‑lock mechanism clamps against multiple rail surfaces, ensuring the mount returns to the same mechanical position every time it is reattached.

How does the 38 mm height affect shooter ergonomics?
It aligns the optic well with modern adjustable stocks and chassis systems, providing a natural head position and consistent eye alignment.

Does the larger tube diameter improve recoil resistance?
Yes. Thicker tube walls reduce flex, and the rigid Spuhr body prevents movement that could cause point‑of‑impact shift.

How does this mount influence parallax sensitivity?
By keeping the scope perfectly aligned and stress‑free, parallax adjustment remains predictable and repeatable.

Is this mount suitable for rapid‑fire or semi‑automatic platforms?
Yes. Its rigid construction and secure rail engagement prevent micro‑shifts under cyclic recoil.

How does rail tolerance variation affect QDP‑5002?
The cam‑lock system compensates for small differences in rail width, maintaining consistent clamping force and alignment.

Does the mount support auxiliary optics or devices?
Yes. The ISMS interface allows attachment of red dots, lasers, and rangefinders directly to the mount.

How does this mount handle large objective lenses?
The 38 mm height provides clearance while maintaining a low enough profile for stability.

What role does the integrated level play on this mount?
It ensures the optic is installed without cant, which is critical for long‑range windage accuracy.

How does this mount compare to fixed Spuhr mounts?
It provides similar rigidity while allowing fast optic removal and reinstallation without loss of zero.
