IMO the best value scope out there especially for a fiddy is the Leupold VX3i LRP. Going to get a few more to replace some of my older scopes.
Here's the 8.5-25x but they also have a 6.5-20x and 4.5-14x.
Comes in at $700-$900. FFP for easy ranging though the zoom but picture won't change much at different zooms with the TMR reticle. Xmas tree reticle could be handy for a Barrett though. Mil/Mil adjustments. And made in the USA.
ETA I threw a spare SFP F-class VX7 Leupold 7-42x on mine for a bit. Way more magnification than needed for the fiddy but the elevation range is fantastic and it's nice to not need a spotter! Going to replace it with the VX3i soon or, possibly, the Mk7.
