BUIS for Acro on Glock MOS + Tango Down plate

[Andy T]

What are BUIS options for Aimpoint ACRO on Glock mounted using Tang Down plate on Glock 19.5 MOS?
Lower third preferred.

I have Dawson MOS RMR-height sights (which are... less than ideal for an RMR) on one gun and Ameriglo GL429s on another. The Dawsons are close to a true lower 1/3 and the better option if one wants functional iron sights; the Ameriglos are there if one absolutely needs them, but I'd describe it as lower 1/5. For pure shooting I prefer the Ameriglos but do fine with either. I know the Dawsons are roughly POA/POI for my 147gr stuff at 25. I haven't printed the Ameriglos at 25 and I probably ought to. I know they seemed about on at 10-15 yards.

I'm using OEM ACRO plates, however.

I also have Dawson on one and Ameriglo 3 dot night sights on another. It sounds like Acro's window is slightly above RMR's.
I don't mind Dawson sights, but they do indeed cover quite a bit of the lower window.
