Spuhr ISMS SP-4902C Ø34mm Tube 9 MIL (38 mm High) Gen 3 Picatinny Scope Mount
"The SPUHR ISMS SP-4902C offers exceptional rigidity with a high 38mm profile, perfect for scopes requiring extra clearance. The 9 MIL elevation adjustment allows shooters to make precise long-range corrections without fuss, while the one-piece design ensures rock-solid alignment. This mount handles heavy optics effortlessly, making it a favourite among PRS competitors and serious hunters alike. Durability and performance come together seamlessly here." - Thomas.
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.
