LEGOs may have a suggested age range of 8 to 12-years-old, but that shouldn’t stop any adult from playing with him, especially if you’re building big boy toys, like a submachine gun.
Brandon Allen has made a variety of both creative and totally cool creations out of the interlocking brick system (Check out his entire gallery here). Allen’s works of art include helicopters, Humvees and, of course, guns!
This Vector SMG made by Allen not only looks awesome, but is fully functioning as well – in this sense that all the parts move as they should. As if that’s not awe-inspiring enough, Allen breaks down the SMG, only to put it back together again.
