Generally, the discussions regarding the SWFA SS riflescopes revolve around the fixed 6x & 10x. I'm familiar with the fixed 10x as I've a couple on hand.

What about the variables? Specifically the 3-9x42mm and 3-15x42mm and their eye relief and eye box. How easy are they to get behind throughout their magnification range? Any case of tunnel vision (blackouts around the edges)?

Typically, fixed scopes are more robust than their variable counterparts. Any issues with the variables holding up and keeping POA/POI, or are they just as hella stout as the fixed Super Chickens?
