Spuhr ISMS QDP-6002 Ø36mm 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: 279 g/9.8 oz

Note: Will not fit the SAKO S20 or rifles with 2-piece rails

• 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 36 mm tube beneficial for heavy tactical optics?
A larger tube allows more internal elevation and windage travel while providing increased stiffness to prevent tube flex, improving tracking accuracy over long ranges.

How does the QDP cam-lock system differ from standard QD mounts?
It uses dual-lever cams that maintain constant, repeatable clamping pressure against the rail, reducing variations in mount seating and ensuring return-to-zero consistency.

Does the mount compensate for small rail manufacturing tolerances?
Yes. The spring-loaded cam system allows minor rail deviations without introducing mechanical stress or zero shift.

How does the mount handle heat expansion during long shooting strings?
The aluminium alloy body distributes heat evenly and resists warping, maintaining tube roundness and alignment even under extended firing.

Can the mount be used with heavy night vision or thermal devices?
Yes. The Ø36 tube size provides enough diameter for secure clamping, while the height ensures clearance for front-mounted devices.

How critical is torque when mounting a 36 mm optic on this QDP?
Precision torque is essential to prevent tube deformation while maintaining full repeatability of the quick-detach interface.

Does the QDP system allow for rapid removal without losing zero?
Yes. The mount consistently returns to the same rail interface thanks to the dual-cam clamping surfaces.

What role does the integrated bubble level play?
It helps verify perfect cant during installation, critical for maintaining consistent horizontal alignment over long distances.

How does this mount distribute recoil forces?
The mount engages the top and side faces of the rail, spreading forces evenly to prevent movement under sharp recoil impulses.

Is the 38 mm height ideal for modern chassis rifles?
Yes. It balances head clearance, cheek weld comfort, and sufficient clearance for accessories and objective lenses.

How does the mount impact parallax performance?
By maintaining a rigid, centered optical axis, it prevents tube deformation that could create parallax errors at distance.

Can this mount be used on semi-automatic rifles?
Yes. Its rigidity and wide clamping surfaces handle the cyclic recoil of semi-automatic platforms without shifting.

What makes this mount suitable for tactical and precision shooting?
It combines a large tube diameter, consistent QDP repeatability, and rigid one-piece construction for stability and precise optics alignment.

How does the mount perform under repeated removal and reattachment?
The dual-cam system ensures that repeated removal does not change optical alignment or zero, provided the rail is standard.
