New Contest Starting Now! This Target Haunts Me
Tell us about the one that got away, the flier that ruined your group, the zero that drifted, the shot you still see when you close your eyes. Winner will receive a free scope!
I read a lot about certain manufacturers making more durable scopes than others (Nightforce seems to be mentioned frequently in this context). What, from a technical perspective, makes a scope durable? Design? Construction? Tolerances? Materials?
Repeatability.....
NF has a long standing reputation for this. I have several of their scopes and they are always on. I have never had one of their scooes fail me or my hunters.

All of the above. Durable, wear resistant material. Thicker/beefier parts. Better environmental seals. Better shock absorbing design (leaf spring, coil springs, quality of spring etc.). Tighter fit prevents sloppy parts from beating each other to death from vibration or rattling. Environmentally resistant adhesives (like epoxy that keeps lenses, illumination emitters, circuit boards) in place or coatings.
Easy enough to make an optic weigh as much as a tank, but can you make a featherweight optic as durable as one.
Durability comes in a few different forms, too. Airgun scopes are not typically very high-end, but they are built to withstand the particular stresses induced by airguns. Airguns can ruin many otherwise durable optics because they recoil sort of backwards, and not all optics are designed to tolerate this. A similar thing happens with larger semiautos (SCAR, M14, etc.) because of the heavy bolt carrier group slamming forward.
