Specifically for eye dominance..... - Champion Traps and Targets EasyHit Shotgun Sight

Yes, this sight is highly visible like many other front sights but what sets this sight apart is my ability to shoot with both eyes and not have one eye overcorrect. On a sight without the 'tunnel' both eyes see the front sight but they are both different. the best explanation is when you look down the bbl with the easyhit front sight, the non-dominant eye does not see the front bead. Thus, I don't have to close the other eye.
If you naturally close one eye to shoot anyway, I suppose you don't need this product....
