SIG SAUER ROMEO5 TREAD 1x20mm + Holosun HE507K-GR X2 Green MRS Combo
This combo pairs a SIG SAUER ROMEO5 1x20mm TREAD red dot (2 MOA red dot reticle) with a Holosun HE507K-GR X2 open reflex sight featuring a green Multi-Reticle System (selectable 2 MOA dot, 32 MOA circle, or circle-dot).
The ROMEO5 TREAD runs on a CR2032 with MOTAC motion-activated illumination and 10 illumination settings (8 daylight / 2 NV). The ROMEO5 shown includes the SIG M400 TREAD mount/base (direct-mount pattern), not a Picatinny clamp. The HE507K-GR X2 uses a side-loading CR1632 battery tray, offers 10 daylight / 2 NV brightness settings, and uses the Holosun K footprint.
