No, I have used plenty of scopes with inadequate eye relief. 2.8" is going to get someone hurt eventually. Just because it is a nightforce doesn't mean that 2.8" is OK. So you guys got away with it. There will be shot presentations that will get you banged with it.
Talus had a Vortex Viper on his 7WSM with only 3.1" eye relief. That thing tapped me in the glasses several times. Shooting a rifle that you know might tap you causes flinches.
I looked at them (SHV) at the SHOT show. They wouldn't let me touch a round off, however.
