These covers teach you to target focus which will improve your competition shooting skills. The cover easily installs over the optic and prevents you from looking through the optic glass to see the target. You must focus on the target with both eyes open and your brain will naturally superimpose the red dot on the target. These are amazing for teaching new optics users the very important skill of being target focused.
Note: Be sure to select the correction version for your Alpha 3 body from the drop down.
