Description

SB18 – QD Dovetail Mount for InfiRay SAIM Thermal Scopes

Quick Detach | Precision Dovetail Interface

The Contessa SB18 QD Dovetail Mount for InfiRay SAIM is a precision-engineered quick detach mounting solution designed specifically for InfiRay SAIM thermal scopes that utilize a dovetail mounting interface. Built for secure engagement, fast removal, and consistent repositioning, the SB18 provides a stable and repeatable connection between InfiRay thermal optics and compatible rifle platforms.

Manufactured by Contessa Alessandro & C., the SB18 incorporates Contessa’s proven QD locking system, allowing the optic to be mounted or removed in seconds while maintaining consistent clamping tension. This makes it ideal for users alternating between daytime optics and thermal systems, transporting optics separately, or transferring a SAIM scope between compatible rifles.

As a dedicated mount, the SB18 ensures correct geometry and alignment for the InfiRay SAIM platform, eliminating the compromises often associated with universal adapters.

Construction & Performance

The SB18 is manufactured from high-strength materials and finished to Contessa’s exacting standards. The dovetail interface provides a rigid mechanical lock, while the QD system ensures consistent engagement each time the mount is installed. When refitted using a consistent mounting procedure, the system delivers repeatability appropriate for thermal optics.

As with all dovetail-based systems, final return-to-zero performance depends on rail tolerances and user technique, but the SB18 is engineered to provide predictable and reliable results under real-world conditions.

Contessa Quick Detach System

The Contessa QD system allows shooters to swap optics efficiently, move an InfiRay SAIM scope between compatible rifles, and maintain operational flexibility without permanent mounting—an important advantage for modern thermal users.

Thermal optics expose what hides. The mount’s responsibility is to remain rigid, repeatable, and quietly dependable.

Frequently Asked Questions (FAQ)

Is the SB18 compatible with all InfiRay SAIM models?
The SB18 is designed for InfiRay SAIM thermal scopes that use the standard SAIM dovetail interface. Always confirm your specific model before purchase.

Does the mount retain zero after removal?
When installed using a consistent mounting procedure, the SB18 provides repeatability suitable for thermal optics. Minor point-of-impact shift may occur due to dovetail tolerances.

Is this a universal dovetail mount?
No. The SB18 is a dedicated mount for InfiRay SAIM scopes, designed for proper fit and alignment.

Can the mount be transferred between rifles?
Yes, provided each rifle uses a compatible dovetail interface. Consistent installation improves repeatability.

Is professional installation required?
Professional installation is not required, but careful mounting is recommended for optimal performance.
