DENVER - SEPTEMBER 13:  A Colt AR-15, now legal with a bayonet mount, flash suppressor, collapsible stock and a high capacity magazine that holds more than 30 rounds, sits on the counter of Dave's Guns September 13, 2004 in Denver, Colorado. Between 1994 and September 13, 2004 these guns could only be sold to law enforcement and military but now it is legal for civilians to purchase them due to the expiration of the Brady Bill.
