Riddick is the third installment in the "Riddick" film series, which began with 2000's Pitch Black and continued in 2004's The Chronicles of Riddick. Vin Diesel returns as the title character for the 2013 sequel.
The following weapons were used in the film Riddick (2013):
Faloc (Danny Blanco Hall), a member of Santana's crew chambers a Smith & Wesson SW99 fitted with a futuristic compensator/barrel weight and a small red dot sight.
Diaz (Dave Bautista) carries a heavily dressed up Desert Eagle as his sidearm in the film. It is fitted with a huge muzzle brake, among others things, to make it appear futuristic.
Shotgun
Winchester Model 1887
Boss Johns (Matt Nable) carries a cut-down Winchester Model 1887 fitted with a rail on top of the barrel and a flashlight in the film. Diaz (Dave Bautista) is also seen with the shotgun.
Rifles
M4A1 Carbine
Several of the bounty hunters of Santana's (Jordi Mollà) mercenary crew carry M4A1 Carbines fitted with futuristic barrel weights, angled foregrips and EOTech holosights. Some have tactical flashlights attached. Dahl also uses one in the film.
Dahl (Katee Sackhoff) uses a Savage 110 BA in the film. It is fitted with a bipod and a custom raised scope mount extending all the way forward to the front rail. She most notably uses it to incapacitate Riddick with the "Horse Tranq" rounds. The rifle is also capable of firing "Barium Shells" for long-range radioactive target tracking, "Stab Shock", and "Explosive Tip" rounds in the movie.
Machine Gun
RPK Light Machine Gun
Diaz (Dave Bautista) carries a heavily dressed up RPK light machine gun in the film. The weapon is identifiable by the tilted drum magazine.
