Zeroing IR lasers can be pretty annoying. With a slaved vis laser it’s quite a bit easier. With a zeroed optic and the right target: EVEN easier. We only recommend zeroing lasers to your optic if you are positive you have a solid optic zero. - #atpialc #bcm #bcmgear #irlaser #nvgs #nods #trexarmskydex #surefire | T.REX ARMS
