Nick Jensen (he goes by Nick Brick on YouTube) is a fan of Titanfall as much as he is a fan of Lego. He combined both interests with this project, the Kraber-AP Rifle, which Titanfall enthusiasts recognize as the bolt-action, one-shot, one-kill sniper rifle pilots can carry.
Not only that, Nick added some special effects to the demonstration, so check your volume. The Kraber has a kick. There's a burn card just for show, too.
