The Acetech Brighter R tracer unit is a compact tracer unit that illuminates green or red tracer BBs as they pass through. These tracer units are only 28mm in diameter and 55mm long making them perfect for SMGs and mid-length rifles, preventing any unnecessary length or weight from being added.
It is constructed with an internal rechargeable Li-Ion battery which takes 2.5 hours to charge (from a USB port only) and will last up to 20,000 shots.
