Product DescriptionBuilt for shooting versatility, the Sightmark T-5 is a compact 5x red dot magnifier that mounts behind your reflex or red dot sight for absolute co-witness. Its flip-to-side, locking quick-detach (LQD) mount lets you transition instantly between 1x and 5x, while the streamlined, low-drag housing reduces snagging on gear and is shorter than previous models.

Fully multi-coated optics deliver bright, sharp views, and external windage/elevation adjustments help center your red dot in the magnifier&';s field of view.
