Just ordered a 3-9 VX-F 30mm tube 3-9x40 with Firedot for $300 from Castle Arms. Good to see they are offering the firedot in many newer models. That's what I missed when the VX-R line got dropped.
I haven't looked through a VX-Freedom yet, but if it compares with a VX-2 It's a good scope. I can hardly tell much difference between a VX-2 and any VX-3 I own. VX-1s were the old VARI X IIs. They're ok and I have owned several but the glass is not of VX-2 quality.
I think a VX-2 is closer to a VX-3 than a VX-1 is to a VX-2 in my opinion. The VX-1 is supposedly 87% light transfer, the VX-2 is 92. The old VX-3s were around 98% or so they claim.
