Holosun 509t mounting

#1
So I was completely mistaken in following the idea of the 509T sharing the mounting footprint of the ACRO.

They are not the same and I can’t see how the two would be compatible.

I’ve had the excellent CHPWS plate holding the ACRO and assumed when the 509T showed up I’d just be able to swap it over.
I was wrong and apologize to anyone who I passed this info on to.

The ACROs cross bar is thinner and sits deeper into the cut than the wider and more shallow 509T cross bar. Both have what appears to be matching rail thickness, but the cross bars are completely incompatible.

Please keep this in mind when choosing your options. I’ll get the correct plate from CHPWS and report if I have any issues with the optic.

Right now the only mounting option I have is the supplied plate to attach on top of a Glock MOS plate. 89580F4C-DF89-42BB-A4EE-5B93FAF445A8.jpeg B6E5223D-34C7-4922-9F93-BF280B8036E2.jpeg F550DEE8-EE53-4191-8980-6B7794304C1E.jpeg

Damn that looks good. Between the solar backup and the greater number of features along with my experience with the 508T, I’d have to say if I ever wanted an enclosed-emitter pistol optic it’d be the 509T

@rudukai13 I have no issues recommending it.

It checks all the boxes the 508t and 507c do and adds the enclosed emitter.
I’ve never had an issue with my RMR but why wouldn’t I want the benefit of increased protection.

Do you know of a plate that lets me mount this to a FN 509 tactical. I really wanted to put a closed emitter optic on it and the acro just out of my price range right now
