Mikey:
I bought this rifle used, so I didn't get an owners manual.
The lever safety (to me) is a redundant feature. There is a crossbolt safety that is very positive, and prevents the rifle from firing. This lever safety requires that you squeeze the lever tight to the stock, as well as disengaging the crossbolt. For me this is very uncomfortable when I'm trying to shoot the rifle with any degree of precision from the bench.
Kurt:
I liked the old half-cock type of safety myself, but that's absent in my rifle, and has been replaced by this dual system.
