An anti-gun Facebook page posted a photo on Sunday that had gun owners rolling their eyes.

The image features a bullet shooting out of the barrel of a rifle — anyone who has ever fired a rifle should immediately notice the problem:

You see it, right? Obviously, no bullet would ever shoot out of a barrel with the shell casing.

“Who is faster than a speeding bullet?” the text in the photo reads. “Nobody.”

It didn’t take long for users on Facebook and Twitter to take notice and mock the anti-gun page for seemingly revealing just how much they know about firearms.

“Bloomberg’s idiot everytown group depiction of a gunshot,” Twitter user @BigFatDave wrote. Yes, really. No, not a parody.”

“Why the f*** is a shell casing coming out of the barrel?” a Facebook user commented.

“You wouldn’t get health advice from your mechanic, why would you want gun safety advice from someone who doesn’t own any?” another Facebook user wrote.

While the image at first appeared to be created by Everytown for Gun Safety, an anti-gun campaign paid for by former New York Mayor Michael Bloomberg, and includes the web address of the group’s official website and logo, the Facebook page it was posted on is not the one the group’s website currently links to.

A spokesperson for the gun control group Demand Action told TheBlaze the Facebook page and image belongs to “cybersquatters,” not Bloomberg’s group.

The Facebook page that uploaded the photo joined the social network on April 17. The group recently said it was working to secure a new Facebook group page after a pro-gun group swooped in and used the group’s name to promote the Second Amendment.

“We’re going through the proper process for transitioning our Demand Action page to ‘Everytown,’ which takes a few weeks, and acquiring trademark protection for both Everytown and Everytown for Gun Safety. Once that happens, we expect Facebook to shoo these cybersquattters politely off this name/page,” a spokesperson for Everytown for Gun Safety told BuzzFeed last week.

The groups behind the pro-gun “Everytown” Facebook page — Gun Rights Across America and 1 Million Moms Against Gun Control — have since reportedly taken down the page following an apparent legal threat, the Examiner reports.
