We would like to present to you Leapers DS3840 4.0'' 30 mm T-DOT collimator. The collimator of closed construction is characterized by high quality workmanship. The tube of the collimator is made of duralumin, thanks to which you gain a reliable and effective optic for your weapon unit or air rifle. The collimator has a 4 MOA T-DOT spot and its intensity and color (red and green) can be changed smoothly using the turret located on the side of the device. The Leapers company used high-quality lenses in the product, which are resistant to evaporation, so the image is bright and clear in the most demanding conditions. The optics of the collimator are protected by two rubber flip-open caps. The collimator comes with a 22mm mount and elevation in its kit, so we are able to mount it on virtually any weapon unit that has a picatinni rail. The collimator fits a CR1620 battery.
