The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF, BATF, and BATFE) is a federal law enforcement organization within the United States Department of Justice. Its responsibilities include the investigation and prevention of federal offenses involving the unlawful use, manufacture, and possession of firearms and explosives; acts of arson and bombings; and illegal trafficking of alcohol and tobacco products. The ATF also regulates via licensing the sale, possession, and transportation of firearms, ammunition, and explosives in interstate commerce. Many of ATF's activities are carried out in conjunction with task forces made up of state and local law enforcement officers, such as Project Safe Neighborhoods. ATF operates a unique fire research laboratory in Beltsville, Maryland, where full-scale mock-ups of criminal arson can be reconstructed.

front bead lines up with the center of the standing breech.

The Monte Carlo comb came to rifles via shotgun stocks. It
rises well above the ordinary comb line of the stock at the
butt and tapers downward toward the point of the comb. This
raised portion of the stock lifts the face of the shooter and his
or her line of sight well above the standard elevation provided
by the classic style. However, the same amount of drop is
