Trijicon SRO Sights

Shop Trijicon SRO sights at Deerford Defense for a broad viewing window, straightforward brightness controls, and easy battery access. Choose a fine 1 MOA dot, a versatile 2.5 MOA dot, or a prominent 5 MOA dot, with black and coyote brown finishes to suit your preferences.

A Wide-Window Reflex Sight for Competition and Range Use

The Trijicon SRO, or Specialized Reflex Optic, combines a large, rounded window with a single illuminated aiming point. Its non-magnifying view leaves room to see the dot and the target around it. A forged-aluminum housing, adjustable LED illumination, and a top-loading CR2032 battery round out an optic designed for target and competitive shooting.

Choose Your Trijicon SRO Dot Size

1 MOA: A Fine Aiming Reference

The 1 MOA red dot covers less of a small aiming mark than the larger SRO dot options. Choose it when you prefer a finer reference within the wide viewing window. Compare the Trijicon SRO 1 MOA optic in black with the 1 MOA coyote brown version; both offer the same dot size and brightness controls.

2.5 MOA: The Middle Ground

The 2.5 MOA dot offers a balance between the smallest and largest red-dot options. It is more prominent than the 1 MOA dot while covering less of a small target than the 5 MOA dot. Explore the Trijicon SRO 2.5 MOA optic in black or the 2.5 MOA coyote brown model for a versatile choice for regular practice and competition.

5 MOA: A More Prominent Dot

The 5 MOA red dot gives you the boldest aiming reference of these three sizes. It suits you if you prefer a larger dot, with the trade-off of covering more of a small aiming mark. Choose the Trijicon SRO 5 MOA optic in black or the 5 MOA coyote brown version without changing the window size or mounting footprint.

Brightness Controls and Top-Loading Convenience

Red-dot SRO optics offer automatic brightness and eight manual settings, including two night-vision-compatible levels. Lock-In mode holds your chosen intensity; Lock-Out mode keeps the sight in automatic operation and prevents accidental button changes. The battery compartment opens from the top, so you do not need to remove the optic from its mount to replace the CR2032.

Black or Coyote Brown?

Black provides a neutral finish, while coyote brown offers an earth-tone alternative. On matching red-dot models, choosing a different housing color does not change the dot size, brightness controls, or RMR footprint. Reticle color is a separate specification: a brown housing does not tell you whether the dot is red or green.

Trijicon SRO Frequently Asked Questions

Which SRO dot size should I choose?

Choose 1 MOA for a finer aiming point, 5 MOA for a more prominent dot, or 2.5 MOA for a middle ground. A smaller dot covers less of a small mark; a larger dot is more visually prominent. The best choice depends on the sight picture you prefer.

Does the Trijicon SRO use the RMR footprint?

Yes, but the SRO housing is larger than a standard RMR housing. Confirm SRO-specific clearance and holster compatibility, not just the footprint. Trijicon advises against a fit that places the front of the optic over the chamber or breech face.

Can I replace the battery without removing the optic?

Yes. The top-loading CR2032 compartment gives you battery access while the sight remains on its mount.

Is there a green-dot Trijicon SRO?

Yes. Trijicon also makes a 2.5 MOA green-dot SRO optic. Reticle color and housing finish are separate choices, so compare the exact model when choosing between red and green.
