I've never used the Tasco. I've compared the luepold and BSA sighters, which are very simliar except one is magetic and the other has rods to fit in your barrel on the end. But still they're both very different when I try them on the same gun. I'm not a big fan of BSA but prefer it to be more accurate than the Luepold, just because it actually hooks onto the end rather than just placed on the end with a magnet. I guess the only real way to find out is it test it against an already sighted in gun, and see which is the closet. Has anyone ever tried the BSA sighter?
