The rail is unnecessary on Sakos, both 25 and 30 mm Optilocks have multiple height options, and here you can see both Optilock types in use
Top one is 85 rem mag finnlight with NX8 4-32 x 50
Bottom one is 75 rem mag hunter with NXS 5.5-22 x 50
I use both with 200yrd zero and they’re good to 1200yrds on Sika
VX5 fit well on the short actions with standard height Optilocks.
