SPECPRECISION Arthur 1X Prism Optic with Red & Green Reticle

SPECPRECISION Arthur 1X Prism Optic with Red & Green Reticle

The SPECPRECISION Arthur 1X Prism Optic is a compact and rugged 1X prism optic designed for shooters who want a crisp, dependable aiming reference in a wide range of lighting conditions. Featuring an etched reticle with selectable red and green illumination, the Arthur 1X provides a clear sight picture for both shooters with normal vision and many users with astigmatism.

Unlike a conventional LED red dot sight, the Arthur 1X uses an etched prism reticle. For many shooters with astigmatism, this can provide a sharper and more defined aiming reference with less starburst, flare, or distortion. At the same time, the true 1X optical system remains fast and intuitive for users with normal eyesight.

Red & Green Illuminated Etched Reticle

The Arthur 1X features selectable red reticle and green reticle illumination, allowing users to choose the color that provides the best contrast for their eyes, lighting conditions, and background.

Because the aiming pattern is etched directly into the prism optical system, the reticle remains visible even when illumination is turned off. This allows the optic to remain functional during daylight use without relying on battery-powered illumination.

Astigmatism-Friendly Prism Optical System

Some shooters with astigmatism may see a conventional red dot as a starburst, cluster, streak, or irregular shape. The Arthur 1X uses an etched prism reticle instead of relying entirely on a reflected LED aiming point.

For many users with astigmatism, this can result in a noticeably cleaner and more defined reticle. Individual eyesight varies, but a 1X prism optic can be an excellent alternative for shooters who have difficulty seeing traditional red dot sights clearly.

True 1X for Fast Target Acquisition

With 1X magnification, the Arthur is designed for fast and intuitive aiming at close to intermediate distances. The optical system provides a natural sight picture while helping users maintain good situational awareness.

43.7 mm Optical Center Height

The Arthur 1X features a 43.7 mm optical center height, providing a comfortable elevated viewing position while maintaining a compact overall configuration.

Optical center height is an important specification when matching a prism optic with other optical accessories or when planning the overall height of an aiming setup.

80–100 mm Eye Relief

The Arthur 1X provides an 80–100 mm eye relief, giving users a practical viewing distance behind the optic. This helps support a comfortable head position and makes the sight easier to use across different shooting positions and setups.

Rugged Aluminum Construction

The Arthur 1X is built with a durable aluminum housing designed for demanding outdoor, training, and range environments. Its shock-resistant construction helps protect the internal prism optical system and maintain dependable performance during repeated use.

With an adjustment range of ±30 MOA and 1 MOA click adjustments, the optic allows straightforward zeroing. Its rugged construction is designed to support stable zero retention during normal use.

Compact and Durable Design

At approximately 90.5 mm in length and 300 g in weight, the Arthur 1X balances durability with a compact form factor. Its 35 mm body diameter and 20 mm objective provide a practical optical package for a wide range of setups.

The optic is rated IPX64 rainproof and is designed to withstand shock, helping provide reliable performance in changing outdoor conditions.

Why Choose a 1X Prism Optic for Astigmatism?

For shooters who see a traditional red dot as a starburst, comma, cluster, streak, or irregular shape, a 1X prism optic with an etched reticle may provide a clearer aiming solution. Because the reticle is etched into the optical system rather than being formed entirely by a reflected LED, its shape can remain more distinct for many users with astigmatism.

The Arthur 1X combines this optical advantage with selectable red and green illumination, allowing users to choose the reticle color that works best with their eyesight and surrounding environment.

For shooters with normal vision, the etched reticle also provides a crisp and intuitive aiming reference, making the Arthur 1X suitable for a broad range of users rather than only those with astigmatism.
