MIAMI, FL - DECEMBER 18:  In this photo illustration a Rock River Arms AR-15 rifle is seen on December 18, 2012 in Miami, Florida. The weapon is similar in style to the Bushmaster AR-15 rifle that was used during a massacre at an elementary school in Newtown, Connecticut. Firearm sales have surged recently as speculation of stricter gun laws and a re-instatement of the assault weapons ban following the mass shooting.  (Photo illustration by Joe Raedle/Getty Images)
