This is the $250 OPMOD Battle Mug, a 24-ounce beer receptacle milled out of a solid 13.5-lb block of aluminum that comes equipped with military-spec rails so you can attach all kinds of scopes and laser sights. "Yeah but why?" WHY?! To make sure you don't miss your mouth, dummy!
Hit the jump for a worthwhile shot of the thing decked out in scopes, a video demo, and a link to the product page.
Thanks to Brian, who drinks his morning coffee out of a live grenade so people don't bother him until after he's gotten his fix.
