Apex tactical makes an adapter plate for the FN509 tactical for the Aimpoint ARCO.
There will be a pic mount you can purchase separately. Should put it at 1/3 lower co-witness I think if I remember from shot show correctly.

They do, MPN 200520.
You will need the picatinny rail for the top of your HK and a riser mount to attack the Acro to the picatinny rail, as there is no current mount for the HK SP5k without the picatinny rail.

The Safariland ALS RDS holsters that also fit the Trijicon RMR will fit with the Aimpoint ACRO.
The Springfield OSP will not be compatible with the Acro.
We do not currently carry a mount for the Ruger 57 and Aimpoint Acro.
