Leupold Mark 4 HD 2.5-10x42
Data Provenance
Who tested: Rokslide field eval (2024-07) — read the original write-up, which is the source of record. Who structured it: Optics Intel. We extract outcomes and cite; the testing labor is theirs.
Sample size: 3 (three serial numbers) — evidence about this unit, not a verdict on every unit shipped.

| 3×36″ | Shift | held the eval, then shifted 0.5 mil on the very next shot (sample #2) |
| Long-term | Shift | confirmed 0.2 mil high on follow-up shooting |
Mount setup
Rings/mount: per manufacturer instructions. Ring torque: 18 in-lb. No torque caveat flagged in the source.
Notes
Three samples; none passed cleanly on demand — outcomes varied unit to unit and with re-mounting.
