This is absolutely real
I knew if I didn't snap a picture of this display, no one would believe me. I saw this at a jewelry store up in Wisconsin. Their Christmas special was on engagement rings. "Buy this for her...get THIS for you, FREE." For her: an engagement ring. For him: a SHOTGUN.
So, obviously, this is an engagement ring promotion for guys who are less than sure of what her answer is gonna be. "You wanna up the odds big fella? Pop the question while clutching a camouflaged shotgun. She'll say yes. Trust us."
