100, The - Season 3
The following weapons were used in Season 3 of the television series The 100:
A Walther P99 pistol is seen in the hands of Bellamy Blake when he betrays Pike (Michael Beach). This gun is also seen in (S3E08) where Pike executes Lincoln. The gun is identifiable by the absence of rails at the front. The Walther pistols however are seen less and less starting Season 3 being mostly replaced by the Ruger KP89.
"Sky People" are seen armed with the Ruger KP89 pistol after defeating Mount Weather forces.
Smith & Wesson Model 60
A Smith & Wesson Model 60 can be seen in "Wanheda: Part 1" (S3E01).
Beretta Mx4 Storm
The Beretta Mx4 Storm can be seen in the hands of the "Grounders" as well as the "Sky People".
The Norinco QBZ-97 bullpup rifle is carried by many of the station security forces when more of them land on the surface of the planet Earth. They are identifiable as being chambered for 5.56mm as indicated by their magazines.
CAA Tactical RONI
The CAA Tactical RONI carbine kit (possibly using a Glock 17 as the internal firearm) is seen again with the "Sky People". The guns are never seen truly firing, though, as every scene with them are CG generated muzzle flashes, which indicates that they may be airsoft replicas.
Mossberg 500 Cruiser
A Mossberg 500 Cruiser is seen in the hands of a "Skaikru" soldier in "Watch the Thrones" (S3E04).
Sky people are seen armed with FN Minimi machine guns. It is unknown whether they always had these guns or if they got them from their assault on Mount Weather.
The Arkadia rover can be seen with a M134 Minigun attached to it at the front. This one however is most likely a mock up.
