Description
Trijicon SRO Red Dot Sight in Coyote Brown swaps the RMR's small rectangular window for a tall, round one — 0.98 × 0.89 in of glass that stops framing the target and starts getting out of the way, which is why the SRO turns up on so many competition and target pistols. This is the 1.0 MOA dot, the finest of the three sizes, and the CR2032 loads from the top so a battery change never costs you the zero.
How It Compares
Want something far more compact for duty or carry? The RMR Type 2 uses the same footprint in a much smaller housing. Prefer a sealed, enclosed-emitter design? See the Trijicon RCR. If a 1.0 MOA dot is finer than you need, the SRO is also made in 2.5 and 5.0 MOA — browse the rest of our competition red dot sights and the wider Trijicon range.
Also available in: Black.
Ideal For
- Competition and target pistols
- Slow-fire accuracy, where a small dot helps you call the shot
- Slides and mounts already cut for the RMR footprint
- Shooters who want to change the battery without re-zeroing

Product FAQs
Why choose the Trijicon SRO in Coyote Brown over the RMR?
The window is the reason, because the SRO's is taller and round, so the dot is quicker to find and easier to track through recoil. The trade is bulk, at 2.2 x 1.3 x 1.4 in and 1.6 oz (45 g) with the battery fitted.
Is a 1.0 MOA dot too small on the SRO1-C-2500021?
For precision work the 1.0 MOA dot is the whole point, because it covers very little of the target. If you shoot faster and closer, the 2.5 MOA and 5.0 MOA SRO dots are easier to catch.
Will my RMR mounts work with the SRO Coyote Brown?
Yes, the SRO shares the Trijicon RMR footprint, so slides and mounts already cut for an RMR will take it. Match your slide cut to the RMR pattern before ordering.
Can I change the battery with the SRO still mounted?
Yes, the CR2032 loads from the top, so nothing comes off the gun and the zero stays put. Runtime is 3 or more years at setting 4.
How bright does the Trijicon SRO 1.0 MOA go?
It offers eight manual levels plus an automatic mode, and two of the manual settings are night-vision compatible.
How big is the window on the SRO Coyote Brown?
The round window measures 0.98 x 0.89 in (25 x 22.5 mm). It is tall and round rather than small and rectangular, so it stops framing the target and gets out of the way.
What are the adjustment increments on the Trijicon SRO?
Windage and elevation move in 1 MOA clicks, with 150 MOA of total travel in each axis.
What is the SRO1-C-2500021 made from and is it waterproof?
It is built from forged 7075-T6 aluminium and is submersible to 3 m (10 ft).
What magnification does the Trijicon SRO have?
It is a 1x sight, parallax-free with unlimited eye relief, so there is no magnification to allow for when shooting with both eyes open.
What is included with the SRO in Coyote Brown?
The box holds the Trijicon SRO red dot sight in Coyote Brown, mounting hardware and a tool, and a CR2032 battery.
What other versions of the SRO are there?
This 1.0 MOA SRO is also offered in Black, and the same sight is made with 2.5 MOA and 5.0 MOA dots. For a far more compact optic on the same footprint the RMR Type 2 is the alternative, and the Trijicon RCR is the sealed, enclosed-emitter design.
How long does UK delivery of the SRO Coyote Brown take?
Estimated UK delivery is 10 business days. It ships as genuine UK stock, so there are no import fees to pay on arrival. Checkout is secured by Shopify.
