Offering the ability to adjust to various lighting environments (red for indoor use and green for outdoor use), this adaptable unit is perfect for a wide range of daytime and nighttime applications including hunting, tactical scenarios and precision shooting. The Close Combat 1x28 Dot Sight's cantilever design enables the unit to be positioned forward on the upper receiver. This feature allows users to mount a magnifier behind it, increasing target accuracy and providing the capability of making longer-range shots. The Close Combat 1x28 Dot Sight is also parallax corrected, ensuring the reticle remains in the same spot regardless of target range and aiming position. It is waterproof (IPX6) , shockproof, and weather proof (-4-140 degrees).
