SIG SAUER | Echo RQ35 Thermal Riflescope | Matte Black

The ECHO RQ35 is the entry point into SIG SAUER's Echo R thermal riflescope line -⁠- a 35mm‑objective scope built for close‑to‑mid‑range work rather than long‑range identification, with a lighter 384x288 thermal core than the higher‑tier RV models. It's built for balance and quick handling on the rifle, connects through BDX 2.0 for streaming and recording, and is rated for about 12 hours of runtime with a swappable 18500 external battery backing up the internal cell.
