I really doubt anyone is using that scope on any Long Range rifle,especially a 338 LM or 50 cal.It doesn't have the adjustment range needed.I like the vortex viper hd series they work great way more features per dollar including mil or moa clicks 1/8 moa or .5 mil and return to zero. They are also Ffp reticle. They use them on .338 laupa's all the time so a fifty shouldn't be a problem I guess I didn't look to see what caliber you got I'm just assuming since you said Barrett its a fifty. They are nicer than the night force (better glass) IMHO.
ill second this.I really doubt anyone is using that scope on any Long Range rifle,especially a 338 LM or 50 cal.It doesn't have the adjustment range needed.
And Vortex's glass is no where near the quality of a Nightforce,the Vortex Razor scope comes close,but it cost more than a Nightforce,and still isn't as good a scope.
