Tremors is a 1990 monster film that stars Kevin Bacon and Fred Ward as local handymen who work small jobs in a desert town of Perfection, Nevada. They along with their fellow citizens find that their town now is in danger from monsters who come from underneath the ground. The film's cast includes Reba McEntire and Michael Gross as Heather and Burt Gummer, a doomsday survivalist couple. The film would subsequently become a cult hit, spawning a franchise that includes several direct-to-video films and a television series, the majority of them having Gross reprising his role as Burt. Recently, Universal and Blumhouse Pictures was looking to revive Tremors as a new series for SyFy with Kevin Bacon returning to star and a pilot episode was shot, but ultimately was not picked up.
The following weapons were used in the film Tremors (1990):
William Moore & Co. 8 gauge shotgun
Burt Gummer (Michael Gross) owns an "Elephant Gun" that is a Belgian-made William Moore & Co. 8-gauge firing solid slugs. The shotgun was provided by Ellis Mercantile for the Tremors film. When it was thrown from the truck to the rock, it was dropped and the stock shattered at the wrist due to the 12.5 pounds that the shotgun weighs.
Winchester 1200 Defender (with pistol grip)
Heather (Reba McEntire) uses this pistol-gripped Winchester 1200 shotgun in Defender Configuration, to shoot off the tentacle of the Graboid attacking Burt in the rec room. The angled pistol grip attached to the back of the receiver makes it a Winchester.
Heckler & Koch HK91A2
Colt AR-15 Sporter II
Heather (Reba McEntire) fires several magazines from a Colt AR-15 Sporter II at the attacking Graboid that breaks into the rec room. When abandoning his home, Burt pauses to ask Heather whether he should take a .458 rifle or an M16A2 Rifle, Heather advising him to take the .458 since it would have "better penetration". However, the weapon is not an M16A2; if you look closely at the rifle while it's on the wall, it has an M16A1-style upper receiver and slab-side lower receiver, which indicate it's an AR-15 Sporter II. None of the firearms used in the film were full auto guns. During this time in the 1980s, so called 'assault weapons' were easy to get from movie armories and you could walk out the door with them, the same as older weapons like WW2 rifles. You did not need a specially licensed armorer on set like movies had to get after the California AW ban.
Winchester Model 1894
The Winchester Model 1894 30-30 caliber lever-action rifle is found on the body of Edgar (Sunshine Parker), who had died of dehydration on a tower. Val (Kevin Bacon) later uses it in the first encounter with the Graboids but ditches it when they're being chased.
Winchester Model 70
Heather (Reba McEntire) has one of these Winchester Model 70s chambered in .375 H&H Mag with a scope in her possession and passes it off to Earl (Fred Ward) when he and Val are about to ride off to Bixby by horseback, he loses it however when his horse is attacked. Heather (Reba McEntire) later totes another chambered in .458 Win Mag at the start of the rec room scene, she carries it again later as the town escapes to the mountains and fires a few rounds at some Graboid dirtmounds. She even says in the film it's a .458 and Burt should bring it due to its better penetration and less ammo to carry.
Steyr-Mannlicher SSG-PII Rifle
Burt (Michael Gross) is mostly seen carrying a Steyr-Mannlicher SSG-PII Rifle in the film. When the Graboid first breaks into his and Heather's basement, he uses this rifle to attack the worm before running empty and moving to the gun wall for more firepower.
IMI Micro Uzi
Colt Single Action Army
Earl (Fred Ward) pulls a Colt Single Action Army from the glove compartment of the truck upon discovering the two road crew workers dead. It is later seen again in his possession when He and Val are about to ride off to Bixby.
Smith & Wesson Model 28
Burt (Michael Gross) hands a Ruger Redhawk revolver with a 5.5" barrel and rubber Pachmayr grips off to Melvin (Robert Jayne) to get him motivated to run to the rocks. Melvin is mad once he finds out the revolver is unloaded when he attempts to fire it at the approaching Graboid dirt mounds. Burt also checks the revolver to make sure it's still empty after retrieving it from Melvin.
Magnum Research Inc. Mark I Desert Eagle
Burt (Michael Gross) wears a Desert Eagle Mark I in a hip holster finished in Brushed Chrome for the remainder of the movie after the Graboid broke into his rec room in which it can also be seen on the gun wall in that scene and at one point Burt fires a few shots into the air from it from the rock in an attempt to distract a Graboid from the others. One was also see on the wall of the rec room.
M8 Flare Pistol
The Gummers' Wall of Guns
As the Gummer's reach for more firepower, the camera pulls back to reveal a massive wall of guns, most of them pistols and shotguns. Several times, the guns on the wall changes position. This scene was filmed over several days and (unfortunately) several locations which meant that the wall had to be re-built from scratch more than once.
