Jurassic Park III
Jurassic Park III is a 2001 sci-fi adventure film directed by Joe Johnston and the second sequel in the Jurassic Park franchise. Eight years after the 1993 Isla Nublar Incident, Dr. Alan Grant (Sam Neill) continues his research on the Velociraptor, however he faces constant pressure by the ensuing infamy of the incident. He is asked by Paul Kirby (William H. Macy) to be a tour guide for him and his wife Amanda (Téa Leoni) to Isla Sorna, though there is more to the Kirby's and their journey than it seems. However, when their plane crashes due to an incident involving a Spinosaurus, the survivors must find a way off the island. The film co-stars Alessandro Nivola, Trevor Morgan, Michael Jeter, John Diehl, Bruce A. Young, and Laura Dern who reprises her role as Ellie Degler née Sattler.
The following weapons were used in the film Jurassic Park III:
"Iron Horn 20mm" (Barrett M82A2)
At the film's beginning, a mercenary named Cooper (John Diehl) demonstrates a heavy caliber sniper rifle that is described (in the closed captioning) as an "Iron Horn 20 millimeter". In reality, the rifle appears to be a Barrett M82A2 .50 caliber sniper rifle, the bullpup variant of the Barrett M82 series. When first testing it at an aircraft boneyard, Nash says that this sniper rifle fires 20mm high-explosive incendiary rounds, is gas-operated and uses a rotating bolt. The rifle is fitted with an AN/PAS-13 Thermal Weapon Sight (TWS), Harris bipod and multi-ported muzzle brake. The rifle can be heard being fired off-screen several times during the first encounter with the Spinosaurus, but none of the rounds seem to hit their mark as the dinosaur appears unharmed.
Heckler & Koch SL8-1
The Marines who land on the beach of Isla Sorna are armed with M16A2 Rifles. Many of them appear to have A1-style (teardrop) forward assist buttons (but in the late 1980s and 1990s these were common field repair items on A2s). Most are likely rubber props. Some of the extras exhibit proper gun safety training by keeping their fingers off the triggers, while others do not.
Heckler & Koch USP
A Heckler & Koch USP is seen in Udesky's vest holster. He is then seen in the background when the T. rex meets the Spinosaurus trying to draw out his pistol, but his pistol is stuck on his holster and disappears into the ground.
Maverick Model 88 Cruiser
Nash is briefly seen with a pistol gripped Maverick Model 88 when he rushes to start the plane.
Mk 19 Grenade Launcher
The Amphibious Assault Vehicles used by the Marines are armed with turret-mounted Mk 19 grenade launchers.
Browning M2HB Heavy Machine Gun
In addition to the Mk 19 grenade launchers, the Marines' Amphibious Assault Vehicles are also armed with Browning M2HBs mounted in the turrets next to the grenade launchers.
25mm Olin Flare Gun
Dr. Alan Grant (Sam Neill) finds an Olin 25mm flare gun and uses it to ignite the boat fuel around the Spinosaurus in the water, ending its attack on the group. It should be noted that in real life, submersion under water would render the flare too damp to fire. The gun used is based an older model that was commercially available under the Winchester "Olin" brand before it became Orion. These flare pistols had a black satin finish and bright orange grips, which are the inverse colours of the current Orion models with white and blue colours.
