...me of the sight. Fully multi-coated lenses, 11 brightness settings, 3 MOA Dot reticle, 1 inch riser mount and unlimited eye relief greatly improve target acquisition speed and accuracy..
Clearer & Brighter Red Dot: Different from other sights which use a cheap single lens, GODREAMIT red dot sight uses a high-quality achromatic doublet lens(also fully multi-coated lens), providing superior control for minimizing spherical aberration, reducing internal light loss and glare, ensuring even light transmission, making the red dot clearer and brighter. Allow you to achieve fast target acquisition more easily..
11 Brightness Settings for Better Target Acquisition: Because of the high-quality materials and innovative structural designs, the brightness setting at each level is brighter than other cheap sights with 11 brightness settings. So you can easily adjust the red dot to the best brightness and quickly aim at the target..
Waterproof & Shockproof & Fogproof Design for Maximum Durability: The waterproof optics are O-ring sealed and will stay dry even go 30cm deep for 30 minutes. The high shock-resistant design makes the sight can withstand bumps, bangs, drops and the rough-and-tumble environment of the field. Nitrogen inside the sight ensures that interi....
