A Laser Zeroing System
Don’t have time to go to the range but you want to ensure that that new optic you got is zeroed in correctly? There is an item that will help you do that.
Bore centered zeroing systems are a cool piece of equipment that help you zero in your sights before you get to the range. These zeroing systems are not perfect, they will not get you a perfect line of sight, you will still have to get to the range to get it done right. These will just help you get closer than you would otherwise by hand.
