Can anyone recommend a laser bore sight for a gamo whisper airgun?
I own over 50 airguns and rifles. I use a Laserlyte bore sight
to initially sight the rifle. They make a sight for .177 to .22 Cal
and a .22 to 50 Cal sight. It fits in the end of the barrel. Make
sure it's snug when you adjust it and remember to remove it before
you fire the rifle. see
