Steins;Gate 0 is a 2018 animated series by White Fox, based on the visual novel by 5pb. It is a sequel to the 2011 anime Steins;Gate, but takes place just before the ending of that series. A few months after failing to prevent scientist Kurisu Makise's murder, university student Rintaro Okabe gives up his 'mad scientist' persona and time-travel experiments to continue living with his childhood friend Mayuri Shiina, resigned to the beta world-line. But when a foreign university unveils an AI based on the late Kurisu's memories, and sinister forces conspire to capture the secret time machine hidden in Akihabara, Okabe is forced to resume his traumatic time-travelling efforts to reach the titular world-line and prevent World War III.
The following weapons were used in the anime series Steins;Gate 0:
The Glock is the most common handgun seen throughout the series, wielded by several characters.
Unknown pistols are used by most of the masked assailants in episode 8.
Suzuha uses an AK-47 during a flashback in the future.
An AKS-74U is used by a masked assailant in episode 8.
SERN soldiers in 2036 use the FN F2000 as their standard rifle in episode 20.
Howa Type 89-F
Japan Ground Self-Defence Force (JGSDF) soldiers are seen with their standard-issue Howa Type 89 assault rifles.
IMI CTAR-21 Tavor
Future resistance fighter Luka uses a CTAR-21 carbine in 2036.
The main rifle of the Stratfor operatives sent to capture the time machine in Akihabara is the M16. It has the handguard of the A2/A4 variants, but fires in full-auto like the A1. For some reason, the rifle is not drawn as accurately or as consistently as the other weapons.
Several operatives, presumably Russians, fire OTs-14 Groza carbines in episode 10.
GE M134 Minigun
An Apache attack helicopter sent by Stratfor is armed with door-mounted M134 miniguns and missiles. A miniature version is also seen mounted on the drone that killed Suzuha's mother in a flashback to her future timeline.
