Death Stranding is a 2019 video game developed by Kojima Productions. It is set in a post-apocalyptic world in the former USA, after an event called the "Death Stranding" that united the worlds of the living and the dead. The game follows a porter called Sam Porter Bridges (portrayed by Norman Reedus) in his attempt to reunite America.
With one or two exceptions, much of the real-world weapons cannot be used by Sam, as his weaponry are fictional firearms developed before or during the Death Stranding era. As with Kojima's previous entries, Metal Gear Solid V: Ground Zeroes and The Phantom Pain, much of the real-world weapons featured in this game are fictional hybrid firearms, though they are closely based on their counterparts from the era where they are in.
The following weapons appear in the video game Death Stranding:
A fictional revolver appears in the game, bearing high importance throughout the game's storyline. It is very heavily inspired by the Chiappa Rhino with a 12 o'clock barrel placement. Sam can briefly use it throughout the near end of the game.
Submachine Guns
M3A1 Grease Gun
M3A1 Grease Guns modified with barrel shrouds and charging handles are used by US soldiers in the WWII flashback throughout Episode 7.
Rifles
Fictional AR15-type rifle
An unnamed rifle heavily based on the modern AR-15 and AR-10, but with a side charging upper receiver is seen used by Clifford Unger (portrayed by Mads Mikkelsen) and his skeleton soldiers summoned by him throughout the episodes battling him. Note the KAC Gangster Grip-style vertical grip with integrated weaponlight, a neat touch regarding Cliff's past as an American special forces operator in Iraq. The rifles used by the skeleton soldiers do not have the vertical griplight installed.
M16 (Visually Modified)
Fictional rifles heavily based on the pre-production AR-15 and AR-10 with elements from the T48 rifle are used by American soldiers during a Vietnam War flashback in Episode 11: Clifford Unger, representing the game's version of the M16. These rifles are equipped with an XM148 grenade launcher, at least for the Vietnam soldiers hunting Sam, as the ambient soldier apparitions that disappear do not come with the attachment. These rifles are very clearly predecessors of the rifle wielded by Clifford Unger and his soldiers.
