SWAMP DEER OPTICS dot sights are shock-resistant and of extremely high quality. Although it is not yet a widely known brand, we believe that these are optical instruments that you should definitely try out and see for yourself. 2. T-1 type dot sight. 11-level brightness adjustment. The maximum brightness is quite bright, allowing for clear visibility even when pointed toward a clear sky. However, if used in dark conditions at high brightness, the dot may be too bright and make aiming difficult. We recommend using a low brightness setting in dark conditions. This adjustment allows for a wide range of situations, from bright outdoor conditions to dark indoor conditions (or night combat). 3. The high mount (included) allows you to set the aiming height when wearing a mask, enabling more tactical sighting. 4. The lightweight and durable 20mm metal high mount can be equipped with various microdots, etc. 5. It is waterproof and fogproof, so it can be used in any weather, and the strong manufacturing process provides excellent vibration damping.
