Trijicon, headquartered in Wixom, Michigan, announced a 2.5 MOA green dot version of the SRO in early May 2026. The new model ships in two anodized finishes, black and coyote brown, and every other detail of the optic carries over from the existing red-dot SRO line. Same housing, same lens, same RMR footprint, same top-loading CR2032 battery. The change is the LED color and the reticle behavior that comes with it.

This is the first time Trijicon has offered a green reticle in the SRO family. Green has been available in the MRO and in several Trijicon rifle scopes for years, and Holosun, Swampfox, and Vortex have shipped green-dot pistol optics across multiple footprints. The SRO Green Dot brings Trijicon into a category its competitors have been working for years, with the same build quality and warranty backing the red-dot version.

The human eye peaks at green, around 555 nanometers in photopic vision. Red sits further from that peak, so a red LED has to push more output to look as bright as a green LED of equal power. On a pistol optic running a coin cell battery, that translates directly into runtime. Run a green dot at setting four where you would run a red dot at setting six, and the CR2032 lasts longer between swaps.

The other practical wins show up in bright outdoor matches and in low-contrast environments. A red dot can wash out against orange targets, sunset glare, or USPSA cardboard at noon. A green dot holds visual contrast against most natural and artificial backgrounds, including foliage, dirt berms, and steel. In fog and haze, green also penetrates better than red because longer wavelengths scatter more in particulate. For a competition or duty pistol that lives outside, the practical brightness advantage shows up on the timer, not just on a spec sheet.

The astigmatism story matters too. A meaningful percentage of shooters cannot see a clean red dot, no matter the brand. The dot looks like a comma, a starburst, or a smear of overlapping points. Green LEDs, especially at small dot sizes, often appear cleaner because the eye processes green wavelengths with less aberration. Trijicon's announcement explicitly calls out astigmatism and red-green color deficiency as reasons green “provides a clearer aiming point” for affected shooters. If you have tried red and seen a smear, this is the most credible upgrade path on the RMR footprint.

Mechanically, this is the SRO you already know. The housing is forged from 7075-T6 aluminum, the same alloy Trijicon uses on the RMR. The window is the SRO's defining feature, a wide circular opening that gives noticeably more sight picture than the rectangular RMR. The battery loads from the top without unmounting the optic, which means a CR2032 swap costs you no zero. Brightness is adjustable across eight manual settings plus an automatic mode that reads ambient light and tracks it.

Adjustments are 1 MOA per click for windage and elevation. The footprint is straight RMR, identical to the red SRO and the Holosun 507C. Weight, dimensions, and waterproof rating should match the existing SRO at 1.6 ounces, roughly 2.1 by 1.3 by 1.1 inches, and 1 meter immersion. None of those numbers move when you swap a red LED for a green one.

For shooters mounting the SRO on a competition pistol or optics-ready carry gun, the implication is simple: nothing about your slide cut, holster, or co-witness sights needs to change. You can keep your existing pistol red dot mount, and the green LED slides in where the red lived. Pair it with the right Trijicon optic across your platforms and the controls and zero process are identical.

The closest direct comparison is the Holosun 507C-X2 in green, which has owned the value end of the RMR-footprint green dot market for years. The 507C runs a multi-reticle system, a shake-awake feature, and a side-loading battery tray, at roughly a third of the SRO's price. Trijicon does not compete on price here. The SRO's case is the larger window, the Trijicon LED quality, and the brand's service record on warranty claims. Shooters who already run an SRO red and want green get a one-for-one swap.

Against the standard RMR HRS, the SRO Green Dot keeps the footprint identical but trades duty-grade impact resistance for the wider sight picture. For uniformed duty use where the optic might take a curb, the RMR remains the right call. For competition, range, and most home-defense pistols, the wider window matters more than the extra ruggedness.

Inside the SRO family, the green-dot version effectively becomes the default pick for shooters who want a single dot size. Trijicon offers the red SRO in 1, 2.5, and 5 MOA. The green launches with 2.5 MOA only. If you were shopping a red SRO 2.5 MOA today and astigmatism or daytime brightness has been an issue, switching to the green version costs nothing in mounting, holster, or zero workflow.

The SRO Green Dot is exactly the product Trijicon should have shipped two years ago. Green-LED pistol optics solve real problems: brighter perceived dot at lower power, longer battery life, cleaner reticle for astigmatic shooters, and better contrast against bright outdoor backgrounds. Holosun, Swampfox, and Vortex have been collecting the customers who wanted those benefits in an SRO-shaped optic. Trijicon now has an answer that costs nothing in compatibility and matches the red SRO mechanically.

The case for buying is strongest for three groups. Existing red-SRO owners with astigmatism who have been working around a smeared dot. Competition shooters running optics-division pistols outdoors where daytime brightness chews through battery life. New buyers shopping the SRO platform who do not specifically need a 1 MOA or 5 MOA dot. The case against is also clear: at Trijicon pricing, a Holosun 507C-X2 GR delivers 80 percent of the practical capability for a third of the cost, and shake-awake plus a multi-reticle system on top. Trijicon buyers are paying for LED clarity, warranty service, and brand. That trade has not changed; the SRO Green Dot just gives Trijicon-loyal shooters a green option without leaving the brand.
