Osight - Osight C Green Dot Multi Reticle

The Osight C Open Green Dot Sight is an advanced reflex optic designed to meet the needs of professional shooters, law enforcement, tactical users, competitive marksmen, and outdoor enthusiasts who require versatility, durability, and precise aiming performance in a compact package.

Built on the Ruggedized Miniature Reflex (RMR/407c/507c) footprint, it offers broad compatibility with a wide range of optics-ready pistols and rifles without the need for additional adapter plates.

A standout feature is the 3 MOA dot and 32 MOA circle multi-reticle system, allowing the user to select dot-only, circle-only, or a combined dot-plus-circle reticle.

The 3 MOA dot is optimized for precision and target engagement at intermediate distances, while the 32 MOA circle facilitates rapid target acquisition at closer ranges. This flexibility makes it suitable for diverse shooting scenarios, from defensive use to dynamic competition environments.

The optic features a large multi-coated lens window that enhances light transmission and reduces glare, resulting in crisp, clear sight pictures that help the eye lock onto the reticle quickly.

This is particularly useful when rapid target acquisition is critical. The generous field of view also aids in maintaining situational awareness during engagements.

One of the Osight C’s practical benefits is its side-loading battery design, which allows the CR1632 cell to be replaced without removing the optic from the firearm.

This ensures the sight remains zeroed and reduces the time and complexity associated with battery changes — a key advantage for users who value both performance and ease of maintenance.

The sight incorporates an intelligent motion sensor that wakes the reticle with slight movement and powers down after about 3 minutes of inactivity to conserve battery life.

A low-battery indicator feature flashes the reticle periodically when the voltage drops below a predefined threshold, letting users know when it’s time to replace the battery.

Crafted from 7075-T6 CNC-machined aluminum with a Type III hard anodized finish, the Osight C is designed for durability and strength, resisting recoil, environmental stress, and rough handling.

It also carries an IPX6 water resistance rating, making it suitable for use in adverse weather conditions without performance compromise.

The optic’s illumination system provides multiple brightness settings, with eight levels for daytime use and two for use with night vision gear, giving shooters precise control over reticle visibility in varying lighting conditions.

Windage and elevation adjustments are made in 1 MOA increments, offering a substantial adjustment range for fine tuning.

With compact dimensions of roughly 45 × 30 × 30 mm and a lightweight construction of about 42 g, the Osight C minimizes added bulk and maintains the balance of the host firearm.

Its RMR footprint compatibility makes it suitable for a broad spectrum of firearms — from compact pistols to rifles equipped with Picatinny high/low mounts.

In summary, the Osight C Open Green Dot Sight delivers a professional-grade reflex optic solution with a versatile multi-reticle system, easy side-loading battery access, motion-activated power management, rugged construction, and wide compatibility.

It is an excellent choice for defensive, tactical, and competitive applications where precision, reliability, and ease of use are critical to success.
