Rifle Scope Mount Camera Adapter - Dual Angle Smartphone Adapter

Our review of the starboosa Rifle Scope Mount Camera Adapter finds it most useful for hunters, birders and outdoor photographers who want simultaneous sighting and observation with a smartphone. The key reason to buy is the upgraded dual-view design: it lets you record or stream the scope view through your phone at a 90-degree angle while still using the eyepiece to aim, which makes documenting shots and sightings far easier in the field. The adapter is solidly built and fits a wide range of phones and eyepieces, making it a practical tool for people who want hands-on control plus a camera perspective.

Key Features

• Dual-angle viewing: Lets you use the phone camera at a 90-degree angle while keeping the scope eyepiece available for aiming, so you can observe and aim at the same time.
• Wide phone compatibility: Accepts smartphones with widths from 58mm to 100mm, covering many popular phone sizes.
• Eyepiece fit range: Works with eyepieces that have outer diameters from 33mm to 46mm, including curved eyepieces and those with knobs or small rings.
• Durable construction: Made from anodized aluminum with nylon plastic screws to reduce scratch risk and improve long-term stability.
• Adjustable exit pupil distance: Designed to be compatible with common exit pupil distances and extendable via an optional extension tube kit if needed.

Who It's For

This adapter is ideal for hunters and birders who want to document sightings or shots without sacrificing the ability to aim through their scope; the ability to view from two perspectives simultaneously is particularly useful during field work and guided outings. It is also well suited to outdoor photographers and hobbyists who already use smartphone photography and want an affordable way to capture scoped images and video.

People who should look elsewhere include users with very unusual scopes that need more exit pupil length than standard adapters provide unless they plan to buy the separate extension tube kit, and anyone seeking fully integrated digital scope systems rather than a smartphone add-on.

Pros & Cons

• Simultaneous first-person and 90-degree third-person viewpoints enable documentation while aiming.
• Broad smartphone and eyepiece compatibility covers many common models and scope types.
• Sturdy anodized aluminum build and nylon screws protect eyepieces and add stability.

Cons

• May require the optional extension tube kit for scopes with unusually long exit pupil distances.
