The following weapons appear in the film Predators:
Predators is the 2010 sequel to the films Predator and Predator 2. Produced by Robert Rodriguez, it stars Adrien Brody as Royce, a mercenary captured and sent to a Predator homeworld along with seven other 'human' predators.
Royce (Adrien Brody), the leader of the humans carries an AA-12 throughout the movie, it is fitted with a drum magazine loaded with Frag-12 rounds, a Surefire M900 weaponlight foregrip, and custom camo paint that appears to be similar to the US Army's pixelized UCP pattern.
Heckler & Koch MP5K
Cuchillo (Danny Trejo), a Mexican Drug Cartel enforcer, is seen with two Heckler & Koch MP5K's strapped to his back, in a manner similar to Chuck Norris' Mini Uzi harness in Invasion USA.
Nikolai (Oleg Taktarov), a member of the Russian VDV Paratroops carries a hand-held M134 Minigun substituting for a GShG 7.62mm machinegun thats described in the script, reminiscent of the gun used by Jesse Ventura in the original film. The gun is later destroyed by a well aimed shot from a Predator. When we first see him use it, the barrels don't appear to be spinning.
Blaser R93 LRS2
Isabelle (Alice Braga), an IDF sniper, carries a Blaser R93 Sniper Rifle fitted with an Elcan DigitalHunter scope (substituting for the Heckler & Koch PSG1 described in the script). In several scenes, we hear the scope adjusting even though she isn't hitting any of the buttons.
Heckler & Koch HK45 w' Compensator
The main sidearm of Isabelle (Alice Braga). She prepares to kill herself with it before a Predator Hound can get her, only to be saved at the last minute.
Beretta 92FS Inox
A Beretta 92FS Inox with custom grips and a compensator is carried by Hanzo (Louis Changchien), a Yakuza assassin who uses it until he acquires a katana.
A Mk 2 hand grenade is seen among the weapons in Noland's (Laurence Fishburne) arsenal. Royce later strings several of them together in a trap for the 'Breserker' Predator.
M18A1 Claymore
When Nikolai sees Noland's weapons cache, he eyes a M18A1 Claymore anti-personnel mine on the table. He's startled because its a Vietnam-era Claymore, revealing just how long Noland has been on the planet.
Nikolai apparently grabbed the Claymore mine offscreen, because he is seen using it prominently later.
Noland's weapons cache
When the group are taken to Noland's cave, they see he's collected a mixture of weapons, some human and some alien. Of the human weapons there are CAR-15, S&W M29 .44 Magnum and an unknown shotgun. There is also an M79 grenade launcher, though it is only used to fire a flare.
