There are always bargains to be found at Goodwill. But one couple in Florida got a bit more than they bargained for when a baby jumper they purchased at Goodwill for $10 turned out to be a Mossberg 715T rifle chambered in .22 Long Rifle. The weapon is a variation on Mossberg’s small caliber Plinkster rifles designed to resemble an AR-15.

According to the story that first circulated on social media before being picked up by a number of news outlets, the Baby Einstein Activity Jumper was purchased on their way to their baby shower. Veronica Alvarez-Rodriguez, who described herself to the Northwest Florida Daily News as a “military wife,” claimed that her husband was “thrilled” when he found the rifle, exclaiming, “you guys got me a gun?” Her husband’s name or connection to the U.S. military has not been released to the public.

According to Alvarez-Rodriguez, the box was taped shut and appeared to be sealed, as though it had never been opened at all. She also uploaded a video, likely in response to comments suggesting that the discovery was a hoax, showing that the rifle does indeed fit inside the box.
