1. Compatibility with Weihrauch HW44

  • Mounting: The HW44 features a Weaver/Picatinny rail, which the SCRD-19II should fit without issue.'
  • Durability: The SCRD-19II is designed for recoil resistance, and the HW44, being a PCP air pistol, has little to no recoil, so it should hold zero well.

2. Suitability for Target Shooting (10/20/30m)

Dot Size: The sight has a 3 MOA red dot, which offers a good balance between precision and fast target acquisition. At:

  • 10m → The dot covers about 9mm of the target.
  • 20m → Covers around 18mm.
  • 30m → Covers about 27mm.
  • This means for precision target shooting, particularly for smaller targets, the dot may cover too much of the bullseye at 30m.
  • Brightness Settings: The SCRD-19II has adjustable brightness, making it suitable for different lighting conditions, whether indoors or outdoors.

3. Suitability for Pest Control (10/20/30m)

  • Accuracy: At 10-20m, the 3 MOA dot should allow for accurate shot placement on small pests like rats or pigeons. At 30m, it may start to obscure finer aiming points, making headshots on very small targets challenging.
  • Parallax & Eye Relief: Being a red dot sight, it provides unlimited eye relief and is parallax-free beyond a certain distance, which helps for fast, instinctive shooting.

Conclusion: Is it Suitable?

✅ Yes, the Vector Optics SCRD-19II is a suitable red dot sight for the Weihrauch HW44 PCP .177, especially for target shooting at 10-20m and pest control at close-to-medium distances.
???? For precision shooting at 30m, the 3 MOA dot may be a bit large, but it depends on the size of your target and your shooting preference.

Alternative Considerations:
If you want more precision for longer ranges (30m+), a smaller MOA dot (e.g., 2 MOA) or a scope might be better.
If your priority is fast target acquisition, this red dot sight should work well.
