Davika QD Mount 57H for iRay RH25 / PFN640+

Davika TSM-01-QD-57H Mount for iRay RH25 / PFN640+

The Davika TSM-01-QD-57H is a multifunctional quick-detach riser mount designed specifically for the InfiRay (iRay) Rico Micro RH25 and PFN640+ V2 thermal devices. With an industry-standard 57 mm (2.25”) optical axis height and rearward cantilevered design, it provides improved eye relief and comfortable operation when wearing tactical equipment or plate carriers.

The TSM-01-QD-57H is primarily designed for using the thermal device as a primary optic, while also providing an integrated interface for mounting a secondary red dot at an angle. It can additionally be used to mount the thermal device as a clip-on in front of a red dot at the same 2.25” height, without requiring additional risers or adapters.

Key Features

57 mm Optical Axis

• 57 mm / 2.25” optical axis height
• Rearward cantilever design provides additional eye relief
• Designed for comfortable use with tactical equipment and plate carriers
• Suitable for primary thermal optic and clip-on configurations

Thermal Device Compatibility

• Designed for InfiRay (iRay) Rico Micro RH25
• Compatible with InfiRay (iRay) PFN640+ V2
• Can be configured as a standalone primary thermal sight
• Can be used as a clip-on in front of a red dot positioned at 2.25” height

Integrated Tactical Interface

• Front section incorporates a dedicated quick-detach interface
• Allows installation of a secondary aiming device
• Supports angled secondary red dot mounting
• Provides rapid transition between thermal and red dot aiming

RDM Ecosystem Integration

• Designed for integration with the DAVIKA RDM system
• Supports red dot, magnifier, and thermal configurations
• Daytime configuration can combine a red dot, FTR magnifier, and TSM-01-QD-57H thermal clip-on
• Nighttime configuration allows the primary red dot and magnifier to be removed and the thermal mount used as the primary optic
• Designed for consistent point-of-impact repeatability during configuration changes

Precision Mounting

• Precision-milled longitudinal recess contacts the Picatinny rail along two narrow parallel lines
• Helps minimize the effect of rail surface imperfections
• Center-cut recoil lug distributes clamping force across two bearing surfaces
• Designed to address rail tolerance variations and prevent shifting under heavy recoil
• Provides repeatable positioning on the Picatinny rail

Quick-Detach System

• Eccentric QD mechanism with adjustable clamping tension
• Tool-free mounting and removal
• Ergonomic lever with dedicated locking button
• Helps prevent accidental release
• Designed for repeatable return-to-zero performance after repeated removal and installation

Construction & Finish

• Manufactured from 7075-T6 aluminum
• MIL-A-8625 Type III Hardcoat Anodized finish
• Stainless-steel fasteners with dark anti-reflective coating
• Drainage channels throughout structural openings and internal areas

Platform Compatibility

• AR-15
• AR-10 / SR-25
