The Holosun 509MNT-1.63-PIC is a genuine Holosun rail mount that carries a 509-series or AEMS-MACRO optic at a 1.63in mount height on Picatinny.
A pistol-pattern enclosed dot has nowhere to live on a rifle until something lifts it to head height. This is Holosun's own answer for their 509 footprint, machined as one piece rather than stacked out of plates.
Holosun machine it from aluminium and finish it hard anodised, quoting a 1.63in mount height and a MIL-STD-1913 Picatinny interface. The compatibility list on their own page covers the Holosun 509 series and the AEMS-MACRO series, which is wider than the model name suggests.
Read that footprint list carefully, because it is the only thing that matters here: a 509T-pattern optic bolts straight on, while an RMR-footprint sight such as a 507C and an RMSc-footprint sight such as a 507K both use different screw patterns and will not. Two things Holosun do not state for this mount are a weight and what hardware comes in the box, so we do not claim either.
Any MIL-STD-1913 rail section will take the clamp; the deciding factor is the optic footprint. For a shotgun, rimfire or any host where the rail already sits high, the lower version is the 509MNT-0.82-PIC. Going the other way and putting a 509 optic onto a pistol slide is a plate job rather than a mount job — see the 509PLT-507C plate for RMR-cut slides or the 509PLT-MOS9MM for Glock MOS.
