This is my concern since there is nothing left if I need it. And yes, it’s the front sight.
And to others no, I’m no expert and said I was new to this platform at the start, but I’m learning. I understand a little, and know there is offset as well, but something isn’t right here. Whatever the case, I’ll get it sorted. Thanks for your help all.
That low at 25 would probably still have you hitting high at 100 so I would would at 100 to check and it'll probably be good.
My standard procedure for zeroing same plane rear irons for POI=POA at 100 yards is to shoot a 25 yard target and adjust so the bullet is roughly 2 inches low at 25 and that will put nearly dead on elevation at 100.

I bought a used "DD" front that wouldn't zero at 50yards(hitting high with the post barely threaded in) so assumed I got a fake even though it seemed to match pictures of some DD sights through the years.
Go here and use 2.61" for the sight height.

What you have seems to be on the ragged edge of being able to get either a 50 or 100 yard zero, but the maxed out part sounds like something is off.

Are you married to DD sights? When you found a problem, you did not contact DD, you contacted BCM and they were just fine with other sights. DD rear does not even adjust for distance. OK, it is cool, sleek, A1 windage, slides on, but these are for up close work only. There is a cut down A2 from LMC and an even cooler design marketed by Palmento. These can be adjusted for distance. Or you could move into the 21st Century with Ultradynes. What is the fascination for DD?
I can't speak to the Marines, but I spend 20 years in the Army and never once confirmed at distance. Never fired at a KD range after basic training. Silhouettes only.
M193 @ 3200 fps is 4" high and M855 @ 3100 fps is 2" high at 300 M with a 25 M zero. From a ballistics calculator because why would I zero at 25 M now that I have a choice?

Just because it's the Army way doesn't mean it's the right way. In fact, that correlation coefficient is probably comically low overall.
Zero at 50yd if you're able to, 36yd if you need to, or calculate how low you need to be in order for you to get a usable 50yd zero.
What lets the 36yd zero work well is that you can line up a 300m BDC to that point, and you end up with something usable... you could do the same with a 400offset at 25yd, but 50/200 is still a preferable point because of the managable 115-125yd offset
