Re: Well I bought one
If you aren't going with a stock and are looking to put it towards a scope at the moment. The $600 for the stock you were looking to get, the $500 originally set aside for glass, gives you $1100.
That could grab you a used NF, the 3.5-15 NXS would not be a bad option at all. These are proven performers, just great all around.
For $800, I would look at Sightron's SIII line of scopes, I currently run one in 8-32x56, probably a bit high on mag for what you want, but they offer 6-24x50 as well as 3.5-10x44.
The Vortex Viper PST is in that range as well, plenty of current reviews on this scope on here.
Between $800-$1100 you can look at Swarovski's Z3 line of scopes.
