i have brand new in packaging (2) Vortex SV-1 switchview throw levers, and (1) vortex SV-3 throw levers. The SV-1 is for the Vipers with the older style Rubber magnification ring. the SV-3 is for the new Gen II razor Scopes. i have aquired these as a result from ordering the wrong ones in pairs twice. lol i need an SV-2, would love 2 of them actually. so if you have some to trade i would do that. otherwise they are all for sale for $35 shipped. again these are brand new in packaging. thanks.
