Jumanji is a 1995 fantasy film directed by Joe Johnston (The Rocketeer, Jurassic Park III) starring Robin Williams with Jonathan Hyde, Kirsten Dunst and Bonnie Hunt. Along with the first Jurassic Park, it was one of the first movies to make extensive use of CGI in a non-fantasy setting.
The following weapons were used in the film Jumanji:
Taurus Model 689
There is a Mossberg 500 in Carl's police cruiser. Monkeys chamber a round and fire a round through the roof.
Winchester 1901 Shotgun
Van Pelt (Jonathan Hyde, in a dual role) initially comes out of the game with a modified Winchester M1901 Shotgun rifle, but runs out of ammunition, which cannot be replenished since it hasn't been manufactured since 1903. The shotgun has been modified with a custom stock, a false box magazine and a large tube placed over the barrel in order to make it appear to be a large caliber elephant gun.
A Daewoo USAS-12 is used by Van Pelt, who acquires it after convincing the gun shop owner to bypass the mandatory waiting period with a bribe. It is outfitted with a scope, drum magazine, and suppressor to make it look like a sniper rifle.
Van Pelt walks past a prominently displayed SPAS-12 in the gun shop.
Heckler & Koch HK94
A Heckler & Koch HK94 is seen being worked on in the gunshop where Van Pelt acquires the USAS-12.
