Thanks Ron,but I wasn't seeking help in finding a mount,I just thought the photo may have been an example of people's confusion about " bullets" vs "cartridges".Without any words that might have gone with the picture it is tough to say. My guess is that he was showing the red dot mounted to his GP100 and the bullets were just to add to the aesthetics of the picture. Or, he was showing the bullets he uses. But when someone is browsing for a mount, the people responding should also describe the mount. Answering the who, what, where, when, why, how, etc. questions is the best way to describe something to help someone looking for information.
