Out Of Stock Spuhr ISMS QDP-3602 Ø30mm Tube 6 MIL (38 mm High) Quick Detach Picatinny Scope Mount
"This high-mount 30mm Spuhr QDP with 20 MOA is tailor-made for modern precision platforms that need extra elevation and optic clearance. Whether you’re running a clip-on thermal, a large objective scope, or a night-vision bridge, the 38mm height provides plenty of room without sacrificing ergonomics. Combine that with Spuhr’s legendary return-to-zero and this becomes a serious tool for long-range and tactical shooters." - Thomas (Online Sales Associate & Product Specialist).
The Spuhr ISMS (Ideal Scope Mount System) is a high-performance mounting solution engineered for shooters who demand unmatched stability, precision, and modular versatility. Its single-piece, billet-machined aluminium construction provides exceptional rigidity, virtually eliminating flex under recoil and ensuring repeatable zero for long-range, tactical, and competition applications.
The system’s diagonally split rings give unobstructed access to elevation and windage turrets, allowing fast and precise adjustments without interference. An integrated levelling system and alignment wedge ensure the optic is perfectly level during setup, critical for extreme-range accuracy and consistent shot placement.
Multiple interface points along the mount allow secure attachment of a wide range of accessories, from lasers and rangefinders to backup optics and night-vision devices, without affecting rifle balance or ergonomics. Machined from aerospace-grade aluminium and finished with hard-anodised coating, the ISMS offers exceptional durability, corrosion resistance, and mechanical integrity under heavy recoil and field conditions.
With its combination of precision machining, modular functionality, and rock-solid strength, the Spuhr ISMS is designed to elevate any rifle platform, providing a foundation for accurate, repeatable, and adaptable long-range performance.

-
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.
- Spuhr ISMS QDP-3602 30mm High (38mm) Quick Detach 20 MOA Picatinny Mount.
Why combine a high optical axis with 20 MOA of cant?
This configuration is designed for rifles running large objective lenses, clip-on devices, or tall chassis systems while still providing the mechanical elevation needed for extreme long-range shooting.
How does the increased height influence recoil behaviour?
Although the optic sits higher, the Spuhr one-piece body resists torsional flex. The QDP-3602 controls the increased leverage from recoil by distributing force through a wide Picatinny engagement surface.
How does the 20 MOA cant improve long-range tracking?
It shifts the erector system closer to its optical center at long distances, improving tracking linearity and reducing the risk of running out of elevation before reaching target range.
Is this mount well suited to clip-on night-vision or thermal units?
Yes. The increased height allows front-mounted devices to clear the rail and barrel, while the rigid alignment preserves optical collinearity.
How does the QDP interface perform on a tall, canted mount?
The cam-locking system ensures the mount always seats against the same rail faces, preventing vertical or horizontal zero shift when the optic is removed and reattached.
Does this model handle heavy optics well?
Yes. The wide ring spacing and monolithic body prevent scope sag or tube flex, even with large, front-heavy scopes.
How does this mount affect parallax sensitivity?
Higher mounts can make eye position more critical, but the consistent geometry of the QDP-3602 keeps parallax behaviour stable once the shooter’s position is set.
Why would someone choose this over a lower 20 MOA mount?
Shooters using large objectives, suppressors, clip-ons, or tall chassis stocks benefit from the added clearance and improved head position.
Does the high mount reduce cheek-weld quality?
On traditional stocks it can, but on modern adjustable-comb chassis systems it actually improves ergonomics by aligning the optic with the shooter’s natural head position.
Is the QDP-3602 suitable for magnum calibers?
Yes. The mount’s recoil lug and clamping system prevent forward movement even under sharp recoil impulses.
How does the mount influence long-range ballistic consistency?
By keeping the optic within its optimal mechanical adjustment range, ballistic solutions remain more accurate and repeatable.
Why is this mount popular for extreme-distance rifles?
It combines elevation capability, optical clearance, and repeatable zero into a single rigid platform, making it ideal for advanced long-range and precision applications.
