Sig Sauer TANGO-DMR 2-12x42mm，34mm 主鏡筒，第一焦平面，側調焦，HDX 玻璃步槍瞄準鏡

The side focus adjustment is smooth and precise, making parallax changes easy in the field. I mounted this on a bolt gun and the first focal plane reticle stays usable at any magnification, which is exactly what I needed for longer shots.

I needed a versatile optic for both range work and hunting, and the first focal plane reticle on this one keeps holds accurate at any magnification. The HDX glass is noticeably crisp and clear even in low evening light, and the side focus dial makes parallax adjustment quick.

First focal plane reticle holds true at every magnification, and the glass clarity at 12x surprised me for the price point. Only gripe is the 34mm tube needs specific mounts, but that’s on me for not checking beforehand.
