Zero your IR laser, converging vs parallel

Some quick thoughts on converging vs parallel zero for your IR laser.

[@GNpatent]

It hurts my brain to think about how many thouands and thousands of hours have been wasted in the military shooting for groups on paper in order to zero an aiming laser. The standard BZO is 300m, if you just converge your laser with your day optic on a 300m E-type then all of your holds within that range are less than the physical offset of your laser diode and your optical centerline. The offset of your beam is still less than the physical offset all the way out to 600m because that's how geometry and triangles and shit work, people! But if the thought of your beam converging with your day optic at 300m and diverging past that up to an inch at 600m, AND 2 WHOLE INCHES AT 900 METERS, you can just converge your laser with your day optic on the furthest thing you can see on the horizon. If that ain't parallel enough for you then you can't be helped. Yes, I'd like a three jr bacon cheeseburgers with a large fry and a choccy frosty.

i think it depends on platform, a AR platform sure, odd rifles would be different.

Awesome video! Can you do a review on your knights clip on? I can’t decide on the L3 clip on or the knights. Thank you.

For the algorithms

Thanks man!

[@craigmelchiano72]

Thank you so much for clearing this up. At the risk of giving myself a brain aneurysm I’m gonna ask a question..please; So if I’ve got my 5.56 let’s say, I know my EOTECH is zeroed at 50 yards. If I put my laser on my red dot at 50 yards I’ll be zeroed at 50, no problem. But if I pick a further object…a tree 500 yards away, and I put my laser on my red dot at that distance, I should be good? Out till about 200 yards, but once my bullet drop happens I’ll do the same holds with the laser I would do with the EOTDCH?

[@mustangduckk]

Put your laser on your red dot at the furthest thing you can see. Then aim with your laser the same way you would with your red dot. If your hold with your red dot at 500 is 2 targets high, hold your laser 2 targets high.

@@mustangduckk i'd be better to use a set distance like 100 meters consistently to verify zero on both units, vs just pick as far as you can see no, the laser will show up in different spots looking into the optic in diff distances . I am going to try it tomorrow on a Hellion, the height over bore for the pic rail is like 3+ inches

[@stayfrosty3720]

The same concept should work through a LPVO right? just zero the LPVO then find somthing far out and align the lazer with the crosshairs?

[@mustangduckk]

In short, yes you want to do the same thing. It’s easy if your LAM has a coaxial vis laser, just go out at dusk and line them up. If you’ve got IR only then you gotta get behind the LPVO with your nods to do it, which is possible just a little less easy.

[@bghiggy]

Is side mounted more difficult with holds than with top mounted?

[@mustangduckk]

Nope. Set your laser to converge with your red dot at the furthest thing you can sight in on. For all practical purposes, your laser will never be off by more than an inch or two.

[@TypeR632]

Setting up a 300blk running subsonic loads. What would you zero your red dot at if doing a converging zero? 100 yards?

[@mustangduckk]

300 blk with subs, 50 or 100 yd. Either one is probably ok. Either way, I’d get the red dot set, then zero the laser to the red dot at a distant object.
