I just wonder whether the christmas tree reticle may prove a bit 'busy' visually for the average joe, compared to the much more simplified reticle of an ACOG, or the Steiner ICS, the later of which is basically like a hunting scope/red dot hybrid reticle.

The reticle is in the first focal plan and is designed to be seen at 8x power, I think that reducing the power to 6x or 4x will just make the "christmas tree" invisible.

Steiner ICS is just old technology . Christmas tree is now almost standard in precision optics and having an etched Christmas tree means even if electronics fail you still have normal and useable sight.

Tech widely available these days so its just a question of when most manufacturers start offering models with digital reticle options,

Interesting that it uses a full 'Christmas tree' reticle...

Thanks for posting this screenshot, since it shows the exact part of the demonstration that I found interesting and curious.

Notice that the distance is 568 yards.  This seems rather curious, as I would expect both reticle and ranging to be in meters.

Also, although range is given as 568 yards, the FCS places the illuminated aiming point precisely on the 500-yard crosshairs.

Wouldn't that result in the bullet hitting well below the point of aim?

I'm not sure by how much. I forgot to note down what the estimated G7 is for the 135gr projectile, so cant put it in a ballistics calculator to see how much.

From the video, he had no problem transitioning bang bang bang from 300 to 600 yards across the saved targets, so the calculations are clearly within torso levels of drop.

I think it's a traditional christmas tree reticle, rather than a bullet drop compensator. After all, the MSPaint measured distance in pixels from the center to the 2 mark is the same as from the 14 to 16 marks (37-38 pixels).

Right, it's not a "500 yards" position, it's a "5 mrad" drop correction.

Thank you.  I didn't know there was a difference. 

Old dinosaur.  Nearly all my guns had iron sights.

Except my AUG, which had a sight reticle like this:

Still a fantastically practical reticle in my book.

Totally agree.  I had no trouble hitting a torso-size steel plate @ 400 yards.

Edit: doesnt wanna include the snip. But have a look at p14. Nothing unexpected, but nice to see i suppose.
