Frequently Asked Questions

How did the Aimpoint ACRO P1 perform in extreme temperatures?

The Aimpoint ACRO P1 was tested in sub-freezing temperatures (29-30°F) and extreme heat (115°F ambient, 165°F optic temperature). In both scenarios, the optic performed without issues, remaining clear and functional, demonstrating its resilience to environmental extremes.

What caused the performance issue with the Aimpoint ACRO P1 during monsoon season?

During high humidity and temperature in monsoon season, the ACRO P1 displayed a white-blue dot and distortion. This was attributed to humidity ingress into the optic's lens, significantly impacting accuracy until humidity levels decreased.

Was the Aimpoint ACRO P1 successfully repaired after the humidity issue?

Yes, after being sent back to Aimpoint, they reportedly added more glue to the brightness adjustment switch area. A subsequent moisture test confirmed the optic appeared sealed, suggesting the repair resolved the ingress issue.

How does ammunition quality affect red dot sight zeroing?

Ammunition quality is crucial for accurate zeroing. Testing showed that while Magtech 115gr produced poor groups, SB jacketed hollow points yielded tight, sub-MOA groups at 20 yards, highlighting the need for consistent ammunition for reliable sight calibration.
