Crimson Trace CTS-25 Compact 1x20mm Red Dot Sight - Matte Black, 4 MOA Reticle

The Crimson Trace CTS-25 Compact 1x20mm red dot sight is a straightforward, no-nonsense optic built for shooters who want fast target acquisition on rifles and carbines without the bulk or complexity. If you're outfitting a hunting rifle, AR platform, or any gun with a picatinny or weaver rail, this compact red dot delivers the speed and clarity you need in the field or at the range—whether conditions are bright, low, or you're shooting under pressure.

The 4 MOA reticle strikes a practical balance: large enough to pick up quickly across varied lighting, precise enough for accurate shot placement at typical rifle distances. Unlike magnified optics, a red dot forces you to keep both eyes open and stay aware of your surroundings—a real advantage in hunting situations or dynamic shooting. The matte black finish is durable and won't catch stray light.

Battery life is measured in years, not weeks. The CTS-25 runs for 10,000 hours on a single CR2032 cell—that's roughly 14 months of continuous use, or several years of normal hunting and range sessions. Crimson Trace backs this sight with the reliability the brand is known for, and the included riser lets you mount it directly to your rifle's rail system with no custom work or expensive gunsmithing.

Frequently Asked Questions

What rifles and carbines can I mount the CTS-25 on?

Any rifle or carbine with a picatinny or weaver rail—this includes AR-15s, AR-10s, modern bolt-action rifles with rail systems, tactical shotguns, and many others. The included riser mounts directly to the rail without requiring custom gunsmithing or adapter plates.

Is the 4 MOA dot size good for hunting and long-range shooting?

The 4 MOA reticle is optimized for typical rifle hunting and mid-range shooting where you want quick target pickup. At 100 yards, a 4 MOA dot covers roughly 4 inches, making it easy to see and center on game or targets. It's not designed for extreme distance precision, but it excels at the ranges most hunters and carbine shooters actually use.

How long does a battery last in the CTS-25?

The CTS-25 delivers 10,000 hours of battery life on a standard CR2032 cell. That's approximately 14 months of continuous operation—or, if you use the sight for a few hours per week during hunting season, the battery should easily last multiple years between replacements.

Does this red dot work in low light and bright sunlight?

Yes. The 4 MOA red dot is designed to remain visible across varied lighting conditions, including bright daylight and low-light scenarios. The 20mm objective and bright LED reticle ensure you'll be able to pick up the dot when it matters most.
