Many who heard that the mass murder of 49 in Orlando had been committed with a weapon nearly identical to the AR-15, the same gun used in several other mass shootings, people wondered – how did the shooter sneak the gun past bouncers in the club?

Well as it turns out, if you are a stocky fellow like the murderer, it’s really not that hard to sneak an AR-15 underneath jeans and a basic polo, with extra rounds in your pockets.

Twitter user Mr. Perfect posted this video to his news feed, though the video’s source seems to be unknown.

In it, a normal-looking man with an impressive beard approaches and surprisingly reveals the massive gun from underneath his normal outfit.

With discussions about how dangerous weapons like the AR-15 are, it’s important to see just how easy it is to conceal a firearm that can murder 50 in minutes.
