How to Quickly Zero Your ATN Thermal Scope Thor 5 XD LRF!

Learn how to quickly and easily zero your ATN Thor 5 XD LRF with the help of Preston from ‪MossyOak‬ University! Using simple materials like cardboard and hand warmers, he demonstrates how to set up an effective target and use the One Shot Zero feature to dial in your accuracy at 40 and 100 yards.

What Is Zeroing?

Zeroing is the process of aligning the point of aim (POA) with the point of impact (POI) at a specific distance. For thermal scopes, this involves adjusting digital windage and elevation settings so that heat signatures on the reticle correspond precisely to where bullets strike.

Step‑by‑Step Zeroing Procedure

A. Bore Sighting

Remove bolt and visually align barrel with target heat source ~25 yards.
Activate laser bore sighter; center digital reticle on projected dot.
Adjust windage/elevation until reticle aligns exactly.

B. Live‑Fire Zero

Position target at zero distance (e.g., 100 yards).
Fire 3‑shot group, aiming at center of heat signature.
Use spotting scope to verify impacts or walk downrange safely.
Measure group’s center relative to POA (in inches or MIL).
Adjust turret: 1 click = 0.1 mrad (~0.36" at 100 yd) or ¼ MOA.
Fire confirmation group; repeat until POA=POI within ±0.5".
Save zero profile in scope memory.

Frequently Asked Questions (FAQs)

Q: What’s the optimal zero distance for hog hunting?
A: 100 yards balances drop compensation and thermal clarity.

Q: Can I zero in freezing conditions?
A: Yes — warm target pouch indoors before range use.

Q: How does zero change with caliber?
A: Heavier bullets have flatter trajectories; always zero each caliber separately.

Conclusion & Best Practices

Zeroing your thermal scope is foundational to accurate, ethical shooting. By following this guide and maintaining thorough records, you’ll achieve consistent performance across conditions. Always verify zero regularly and adjust for environmental factors to stay on target—day or night.

Happy zeroing and safe shooting!
