Burt Gummer's (Michael Gross) "Elephant Gun" is a Belgian-made William Moore & Co. 8-gauge firing solid slugs. It is used to finish off the Graboid that busts into Burt's rec room. 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.
An interesting goof in the scene where Burt uses the gun to kill the graboid is that when he fires the gun, he has the stock under his arm instead of against his shoulder. If he had been firing actual 8ga. slugs, the recoil would've, at best, flung the gun out of his hands or, at worst, would've broken his wrist or flung the barrel of the gun up into his face.
Burt (Michael Gross) uses a Remington 870 to fire multiple shots at the Graboid in the rec room and then uses it to break the glass on the case containing the elephant gun.
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.

This shot was done months after the end of principal photography on the special effects stage where they were filming the graboid puppet. In the film you see a brief glimpse of a foot, which is that of one of the technicians, not actor Michael Gross.
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
This 30-30 caliber lever-action rifle is found on Edgar's (Sunshine Parker) body 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.
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.
When the Graboid first breaks into Burt and Heather's basement, Burt (Michael Gross) first uses his Steyr-Mannlicher bolt-action rifle on the worm before running empty and moving to the gun wall for more firepower.
A Micro Uzi can be seen near the finale, when Val (Kevin Bacon) fires it over the side of the trailer at a Graboid under the dirt. It could be just a semi auto pistol version.
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.
Earl (Fred Ward) has a Smith & Wesson Model 19 in his possession near the end of the film and fires multiple shots over the side of the old semi trailer as the Graboids attack.
Heather Gummer (Reba McEntire) also takes a nickel SIG-Sauer P226 off the wall to fire at the Graboid along with the Redhawk. She later appears to keep the SIG in her holster.
Burt (Michael Gross) hands a Ruger Redhawk revolver 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 (Michael Gross) wears a Desert Eagle 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.
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.
