The Lost World: Jurassic ParkThe Lost World: Jurassic Park - Internet Movie Firearms Database - Guns in Movies, TV and Video GamesThe Lost World: Jurassic Park
Roland Tembo (Pete Postletwiate) is seen in the film using an LAR Grizzly Big-Bore, made out to be a single shot tranquilizer gun. Sarah Harding (Julianne Moore) is later seen using the same tranquilizer rifle to shoot the T-rex while in San Diego. Some of the hunters are also seen using LAR Grizzlies, outfitted with dual pully drums and made to look like grapple firing guns.
Lindstradt Tranquilizer
Eddy Carr (Richard Schiff) is seen using a bolt action tranquilizer rifle with the name "Lindstradt" clearly shown on the side and a thread-on barrel. It is most likely a mock up of a real rifle but the make is hard to tell. Ian Malcolm (Jeff Goldblum) is also seen holding this gun in some scenes.
Tranquilizer Rifle
Some of the hunters are seen using little tranquilizer rifles which appear to be C02 powered air guns.
Note: The optical sight is infact a Bushnell HOLO-sight. And it is mounted the right way.
Heckler & Koch HK91
Dieter Stark (Peter Stormare) carries a H&K HK91 with an entrylight and telescopic sight attached but is never actually used. Some of the other hunters are also seen using HK rifles and a police sniper is seen hanging out a chopper door with one.
SPAS-12
Carried by one of the hunters is a SPAS-12 shotgun but it is never used on screen.
One of the hunters is seen firing an AKMS while being chased by the T-rex. Based on the stock configuration, it looks like a Romanian AKMS.
Elephant Rifle
Roland Tembo (Pete Postlethwaite) keeps a .600 Nitro double barreled rifle, a well known rifle for Elephant hunting, which seems fitting for use on a Tyrannosaurus Rex.
Two examples were made for the production of this movie by Searcy in the U.S. Steven Spielberg is said to own one of them himself. The location of the other is unknown, but no doubt in the hands of a collector or hunter. These two examples are "real" and meant to be used, and, as with most high-grade double rifles, their value is in the area of many thousands (over $55,000, given their provenance) of dollars each.
M1911A1
The guards in the San Diego dinosaur zoo are armed with M1911A1 pistols. When attempting to stop Ian Malcom (Jeff Goldblum), Ian says if they really want to stop them, to shoot them.
