So I just ordered a Vortex Viper HS LR 4-16x50 FFP and I need to mount it on my Sako Finnlight in 300WM. I think I want to go with the Optilock Ringmounts (single piece) but are there any benefits to the 2-peice Optilocks or the Talley's? Also, does anybody have experience with the clearance with the Optilocks on a 50mm objective? What are the lowest rings I can go with? I would go somewhere and figure it out myself but those Sako mounts are not easy to come across.
