The Holosun 507C-PIC-MOUNT is Holosun's own Picatinny rail mount for its RMR-footprint pistol optics — the 407C, 507C, 407COMP, 507COMP and 508T.
It takes a sight designed to live on a pistol slide and gives it a rail to live on instead, which is how most of these optics end up on a shotgun rib or a rimfire in this country.
Holosun machine it from aluminium with a black anodised finish, cut with the bosses and screw pattern of the full-size RMR footprint. It clamps to any rail section cut to MIL-STD-1913. Holosun's own box contents list the mount by itself, so check what screws came with your optic before the mount arrives.
On a rib-railed shotgun, a pistol-calibre carbine or a railed rimfire it puts a bright, parallax-free dot exactly where a proper rifle optic would sit, for a fraction of the bulk. The limitation is straightforward and worth repeating: this is the large RMR pattern only. A 507K, 407K or any other K-footprint sight uses the smaller RMSc pattern and will not bolt to it.

What the 507C-PIC-MOUNT fits
Picatinny rail on a shotgun rib, a carbine receiver, a rimfire or an airsoft host, carrying an RMR-footprint Holosun. Enclosed 509-series optics use a different pattern and need the 509T Picatinny Mount at 1.63in lower 1/3, while pistol slides are covered by the plate range, such as the 509 plate for 507C and RMR-cut slides. The optics themselves are in RMR Footprint Red Dot Sights.
