Anyone have any experience with these? I was looking at the chamber version and wanted to get one to help sight in the new scope for my AR but I have heard mixed reviews about brands. Ive seen them from $8 on Amazon to $70 at Cabelas. Just curious anyone else's thoughts/experiences before I potently waste money on one.
