Glock 17
The Glock 17 is held by Natasha Romanoff/Black Widow (Scarlett Johansson) when she's confronted by Crossbones' operatives. Bucky Barnes (Sebastian Stan) also uses the pistol to take a shot at Tony Stark (Robert Downey Jr.) during his initial escape from the UN prison in Vienna. Some GSG-9 officers are armed with the Glock.

Beretta 92FS Inox
What appears to be a Beretta 92FS Inox was carried by one of Crossbones' operatives when confronted by Black Widow at the CDC in Lagos. This also appears to be the pistol used by the Winter Soldier in surveillance footage.

Shotguns

Kel-Tec KSG
Crossbones (Frank Grillo) can briefly be seen carrying a Kel-Tec KSG at the beginning of the film. Only the stock is visible.
Strangely, Crossbones is carrying several magazines for weapons he doesn't use. There is a Beretta 92FS magazine on his chest rig, and a Steyr AUG mag and what appear to be Glock mags on his shoulder. Despite this, the only weapon we see him carry is the KSG (in fairness, he has a bandoleer of 12 Gauge shells on his left shoulder).
Rifles/Carbines
AK-103
Zemo (Daniel Brühl) and another soldier are seen carrying AK-103 rifles in a photograph. Russian soldiers in 1991 are also seen with AK-103s while guarding the Winter Soldier lab. The latter is an anachronism as the AK-103 wasn't developed until 1994.

Galil MAR
Some of Crossbones' operatives are armed with the Galil MAR. Captain America oddly identifies this and all other weapons used as "AR-15s".
Galil MAR - 5.56x45mm
An operative carrying the Galil MAR is disabled by Falcon.
DSA SA58 OSW
What appears to be a DSA SA58 OSW is used by Crossbones' operatives.

Machine Guns
FN M240
What appears to be an M240 machine gun fitted with a DI Optical DCL-110 sight is mounted on a helicopter. While the DCL-110 (mounted to a Steyr AUG A3) was portrayed as being a fictional sight capable of seeing through walls in Captain America: The Winter Soldier, it is used for its actual purpose in Captain America: Civil War.
