I have been shooting serious competition for about 3 years now and have never figured out why some scope shooters extend their sight bar out 9-12" . I seen a semi pro shooter at a local indoor range last week with (no joke) his sight extended out 20-25" . It looked as if he made it with a broom handle or something. I have actually tried extending mine and all it got me was a bigger sight tape. Does anyone any insight to this practice.
