XS Sights CSAT Rear Sight for AR-15/M16 Mil-Spec – .070 & .200 Aperture, Steel Black

Upgrade your AR-15 or M16 A2-style platform with the XS Sights CSAT Rear Sight, engineered for shooters who demand fast, reliable target acquisition in both precision and close-quarters combat (CQB) environments. Designed to fit standard Mil-Spec AR-15 and M16 A2 rear sight assemblies, this dual-aperture sight delivers exceptional versatility without the need to re-zero between modes.

The innovative same-plane aperture design allows seamless switching between a .070 precision aperture—zeroed at 100 yards—and a .200 battle aperture notch zeroed at 7 yards, effectively eliminating the 2.5″ offset common in CQB situations. Serrations machined into the face of the aperture reduce glare and help maintain a clean sight picture under varied lighting conditions.

Constructed from durable steel in a matte black finish, the XS CSAT Rear Sight is built to withstand demanding field use while maintaining a slim, functional profile. Its intuitive design promotes instinctive target acquisition, making it an ideal upgrade for tactical shooters, competitive marksmen, and home defense applications alike.
