Night Pearl Two-Piece Adapter for Guide

• Two-piece adapter design: The split construction makes the adapter easier to fit around the objective end of a daytime optic, giving a secure connection for a thermal clip-on without a complicated installation process.
• Guide mounting standard compatibility: Built for the M33.5x0.75 Guide interface, it provides the correct mechanical connection for compatible clip-on devices, helping maintain a stable and repeatable setup in field use.
• Wide diameter compatibility: Support for multiple rear diameters, from 30 mm up to 80 mm, allows the adapter to be matched to many different daytime optics instead of limiting it to one housing size.
• Aluminium construction: The metal body gives the adapter the rigidity needed for dependable alignment while keeping weight reasonable for a clip-on system carried and used outdoors.
• Made in the Czech Republic: European production fits Night Pearl’s established focus on thermal and night-vision equipment, giving this accessory the same practical, system-based approach as the brand’s electro-optic products.

About the Night Pearl Accessories Series

Night Pearl Accessories is the brand’s supporting hardware family for mounting night-vision and thermal clip-on devices to daytime optics. The series is built around a simple requirement: a clip-on system must attach quickly, fit the host optic correctly, and do so in a way that supports repeatable alignment in practical use. Within the range, Night Pearl offers adapter solutions for different clip-on platforms and optic diameters, including threaded and insert-based configurations for selected systems.

A defining trait of the series is its emphasis on interchangeable fit solutions. Adapter size is chosen according to the external objective diameter of the daytime optic, which allows the same general mounting concept to be applied across riflescopes, binoculars, monoculars, and even cameras where compatible. Night Pearl also describes these adapters as designed to preserve riflescope zero without further adjustment, which is especially important when a clip-on is added to an existing daytime setup. In practice, the series serves hunters and other users who need a secure, purpose-built interface between a daytime optic and a thermal or night-vision attachment.

About the Night Pearl Two-Piece Adapter for Guide

The Night Pearl Two-Piece Adapter for Guide is a dedicated thermal clip-on adapter made for devices that use the Guide mounting standard (M33.5x0.75). Its role is straightforward but important: it creates the mechanical link between a compatible clip-on unit and the front of a daytime optic, so the thermal attachment can be mounted in the correct position for stable use. Because clip-on systems depend on consistent alignment, the quality and fit of the adapter matter as much as the device itself.

The two-piece layout is especially practical for users who want a secure fit around the objective housing without relying on an overly complex mounting method. Combined with the aluminium body, it gives the adapter the stiffness needed for dependable support while remaining suitable for field carry. The black finish keeps the appearance discreet and consistent with most hunting optics and tactical optics setups.

This model is also notably versatile in fitment. It is compatible with a broad range of rear diameters, including 30 mm, 38 mm, 41 mm, 42 mm, 48 mm, 49 mm, 50 mm, 56 mm, 57 mm, 58 mm, 59 mm, 60 mm, 62 mm, 62.5 mm, 64 mm, 65 mm, 66 mm, 67 mm, 79 mm, and 80 mm. That wide sizing range makes it useful for adapting Guide-format thermal clip-ons to many different daytime optics, provided the objective outer diameter matches one of the supported sizes.

About Night Pearl

Night Pearl was established in the Czech Republic in 2009 and focuses on electro-optics for low-light and no-light use. Its range covers thermal imaging, night vision, digital night vision, and daytime optics, with products that include handheld devices, clip-ons, rifle scopes, monoculars, binoculars, sights, and adapters. The brand completed its first device, the NP-22 night-vision clip-on, in 2008, and it has produced thermal imaging devices under its own name since 2014.

The company expanded its technical base in 2016 by opening a research, development, and manufacturing facility in Bystřice pod Hostýnem. That background is relevant here because Night Pearl’s accessory products are part of a broader system approach built around clip-ons and related mounting solutions. In 2023, Night Pearl USA began operating in Sarasota, Florida, extending the brand’s presence for the American market.
