As some may already know, Trijicon's manual offers little or no specific info/help in sighting-in the optic, so I'm on my own to sight-in the 3x24 ACOG(triangle ret.) to my 16" A2 carbine.

There was once a post here by a member that I found very useful --gave all the data and trajectories, recommended a 50m zero, but because of the limited <search> features on this site I can no longer find it.

I can probably figure it out on my own, but I'd be a fool to not ask the seasoned guys here first. Right?
Any helpful hints, tips and hard data are welcome.

T.I.A.

Its tacked at the top of this forum- "The Big ACOG BDC Chart". If you ask nicely, Bartholomew_Roberts would probably give you any other info you need.

If you're mounting it on a carry handle zeroing with the tip of the triangle at 50 yards will give you a usable trajectory to 300y. The round will stay within 4" (close to 3.5") from muzzle to 300 yards or so with a 16" barrel. The other option is to zero it at 75 yard. It produces a rather flat trajecotry (with an inch or two) of the point of aim from 50 yards to 200 yards or so. If your mounting with the flattop mount then the 50 yard zero is best (trajectory tables & charts can be found in the zeroing section at MD-AR15.com).

Thanks guys. 75yd zero looks even better to max out at 200yd since M193 out of a 16" barrel ceases to reliably fragment short of 200yd anyway.

To be precise, 140-150m !
