How to Choose the Right Red Dot for the Sauer S 100 Fieldshoot

When selecting an optic for your Sauer S 100 Fieldshoot, here’s what I recommend considering:
Mounting System Compatibility – Ensure the optic includes or supports a Picatinny or Weaver base that aligns with your rifle’s receiver rail.
Dot Size – A 2 MOA dot is ideal for precision shooting; larger dots (3–6 MOA) work better for quick acquisition.
Durability – The Fieldshoot’s recoil demands a solidly constructed optic (7075-T6 aluminum preferred).
Battery Life & Power System – Solar or motion-activated systems like those in Holosun or Sig Romeo models add long-term reliability.
Parallax & Glass Clarity – Choose optics with minimal distortion and crisp edge-to-edge glass clarity.
Shooting Purpose – Tactical, competitive, or hunting — each use case may favor a slightly different design emphasis (window size, controls, etc.).

FAQs

1. Can I mount a red dot directly on the Sauer S 100 Fieldshoot? Yes. The rifle’s rail accommodates most Picatinny or Weaver-based red dots without modification.
2. What’s the best red dot size for precision shooting? A 2 MOA dot provides the most balance between accuracy and target acquisition speed.
3. Does the Sauer S 100 Fieldshoot require a riser mount? Not necessarily. For most optics, a low or medium mount offers the correct eye alignment.
4. Are red dots durable enough for .308 or .30-06 recoil? All optics listed here handle recoil effectively, particularly the Aimpoint and Trijicon models.
5. How long do these optics hold zero? Properly torqued mounts should hold zero indefinitely; even after several hundred rounds, these optics remain stable.
6. Which red dot works best in low light? Trijicon MRO and HOLOSUN 510C both excel due to superior coatings and brightness adjustment.
7. Can I use these optics with magnifiers? Yes — Aimpoint, Trijicon, and HOLOSUN red dots pair excellently with 3x magnifiers for extended range shooting.

Conclusion

The best red dot for Sauer S 100 Fieldshoot ultimately depends on how you shoot — but if I had to pick one all-around winner, it would be the Aimpoint Micro T-2 for its unbeatable combination of precision, endurance, and optical clarity. The HOLOSUN 510C offers unmatched versatility for its price, while the Sig Romeo5 gives tremendous value for everyday shooters.
