STA,
Are you set on a variable? These fixed are pretty nice. I have the older 10x MIL reticle/MOA turrets on my 5R Milspec and am going to 'upgrade' to the new MIL/MIL reticle design possibly in 12x or 16x (maybe 20X, this isn't a close range rifle). You can also get a side adjust parallax model. They're shorter and lighter than the Viper.
The Viper is sweet though, had one of the PSTs on order when they were coming out, but took so long to come in hunting season forced a different choice. Still like the PST but the SWFA SS scopes are hard to beat for price. And I'm always at the 'right' mag for ranging!
