I have several swfa fixed scopes--they are great for the money, but have their limitations as well. their glass tends to distort at the edges, no big deal for me. One of their biggest advantages is their extra-sharp fine reticle, the little diamonds in particular I find very useful for getting focus/parralax adjusted at long distance. They are built to take punishment--in other words quite heavy. They were unavailabe for a long time--glad to see they are back in stock.
