Overview
The SightMark T-3 3x Magnifier is designed to enhance your sighting system by providing a 3X magnification, allowing for improved target acquisition and accuracy at extended ranges.

This magnifier is commonly found in builds utilizing a mid-length gas system and chambered in 5.56 NATO, making it a suitable choice for a variety of tactical applications.
