I must chime in again as my vortex viper and is always on full magification and is mounted on my 7mm mag and though I didn't hit myself I feel it brushing my glasses so as I need bi-focals I maybe giving a skewed or unfair post to that extent please note this! And when I shoot my other scopes they offer to me in my glasses a better eye relief, and my earlier post is informative to eyeglass wearers not to flame the quality of the glass or the scope.... As this is the Highroad I feel I must abide by our standard.
