The Holosun HS507C uses the RMR footprint. So the Leapers UTG Pro Super Slim RMR 45 Degree Angle Mount will work with that red dot.
Only if the Trijicon SRO has the same footprint as the RMR series.
No, this is only for optics with the RMR footprint.
The Leapers UTG Pro Super Slim RMR 45 Degree Angle Mount is designed to fit optics with the Trijicon RMR footprint, it would not be compatible with the Romeo 1 which uses a proprietary footprint.
If you are referring to the Sig Romeo Zero, then this Leapers UTG Pro Super Slim RMR 45 Degree Angle Mount would not be compatible. We do carry the Arisaka Defense Offset Optic Red Dot Sight Mount (found in the link below), and the Arisaka Defense Offset Optic Plate (found in the link below) for the DeltaPoint Pro footprint. You will need both pieces to mount the Romeo Zero.
