TSM Series Thermal Scope Mounts | 38mm & 57mm Optical Heights

A modern thermal imaging device is more than just a scope — it is a universal thermal module that can function in several roles:

• As a primary thermal scope — dedicated thermal optic for hunting or tactical use
• As a clip-on thermal mount — mounted in front of a red dot sight (RDM series)
• As a clip-on thermal mount — mounted in front of an LPVO or magnified optic (MSM/RSM series)
• As a helmet-mounted monocular — for navigation and situational awareness

The TSM series is built around a universal geometry concept, allowing one thermal device to serve multiple purposes. Simply change the mount configuration — not the optic.

Zero Retention & Repeatable Mounting

DAVIKA TSM series thermal scope mounts are engineered for repeatable zero retention — even after removal and reinstallation. Key features include:

• Precision-machined contact surfaces for consistent alignment
• Full compliance with Picatinny MIL-STD-1913 / STANAG 4694 standards
• Rigid locking mechanism with no play or shifting under recoil
• Return-to-zero performance — remove your thermal optic for storage or transport, reattach it, and maintain point of impact without re-zeroing

This is critical for professionals who need to swap optics between platforms or store thermal devices separately from their weapons.

Optical Axis Height: 38mm vs 57mm — Which One Do You Need?

The TSM series is available in two optical axis heights. Your choice depends on how you plan to use your thermal device.

38mm — Optimized for Clip-On Use

• Ideal for use as a clip-on thermal mount in front of a red dot or LPVO
• Compatible with most LPVO and magnified scopes (industry standard 38mm optical axis)
• Can be mounted on a 19mm riser to achieve 57mm total height (compatible with RDM series)
• Also works as a primary scope for some platforms

57mm — Optimized for Dedicated Thermal Scope

• Designed for use as a dedicated thermal scope mount
• Matches the "one optical axis" concept for AR-platform rifles (coincident with RDM red dot mounts)
• Allows co-witness or lower 1/3 co-witness with backup iron sights
• Compatible with offset red dot mounts for secondary aiming devices

Most LPVO scope mounts on the market use a 38mm optical axis, ensuring proper alignment when using a thermal as a clip-on. The 57mm height corresponds to modern AR-platform ergonomics and matches DAVIKA RDM red dot mounts for a unified optical axis across multiple aiming devices.

Full Integration with DAVIKA Ecosystem

TSM series thermal mounts are not standalone products — they are part of a fully integrated ecosystem of DAVIKA mounting solutions:

• Single optical axis with RDM series red dot mounts (57mm configuration)
• Compatible with MSM/RSM series scope mounts for magnified optics
• Modular design allows you to reconfigure your weapon for different missions without rebuilding the entire system

Whether you are running a red dot alone, a red dot with magnifier, an LPVO, or a thermal clip-on — DAVIKA mounts work together as a unified system.
