This is the $250 OPMOD Battle Mug, a 24-ounce coffee (or beer!) mug milled out of a 13.5 lb. block of solid aluminum. The tacti-cool mug comes equipped with a removable A2 carry handle and three mil-spec rails so you can attach all sorts of scopes, lights, and sweet mall-ninja add-ons.
Who would have ever thought you could mount a bipod, 3 lasers, 2 flashlights, nightvision, an Eotech sight, foregrip, can opener, and an angled scope to a coffee mug!? And more importantly, WHY?!
