The X-Files - Season 4

The X-Files - Season 4 Country USA Channel FOX Genre Science-Fiction Investigative Thriller Broadcast October 4, 1996 - May 18, 1997 No. of Episodes 24 Main Cast Character Actor Fox Mulder David Duchovny Dana Scully Gillian Anderson

Season 4 of The X-Files premiered on October 4, 1996. Like all previous seasons of the show, the fourth season was filmed in and around Vancouver, British Columbia. Season 4 would bring several new elements, both off-screen and on, to the series. New characters and actors were introduced, including Laurie Holden, who would play Mulder's new informant Marita Covarrubias, and Chris Owens, who would play the younger version of 'The Cigarette-Smoking Man'. Both of these actors would make additional appearances throughout the rest of the show. In addition, the background alien conspiracy mythology was expanded considerably with several new elements, including the revelation of the use of altered Africanized Honey Bees (an aspect that would be a paramount plot point for the 1998 feature film), while several 'Monster of the Week' episodes would continue touching on dark and light tones alike, and would feature several noted guest actors, including Tom Noonan and Paul McCrane.

Off-screen, writing duo Glen Morgan and James Wong, following the cancellation of their own series Space: Above and Beyond, returned to write episodes for the X-Files' fourth season; several actors from their show would also be featured in S4. Many episodes in Season 4 would prove to be considerably remarkable - Among these would be "Home", the first episode in the season written by Morgan and Wong, which would be the first episode in the show to be given an explicit 'viewer discretion advisory' for content; "Unruhe", which marked the change in the show's previous airtime slot from Friday evening to Sunday evening (where the show would continue to air for the remainder of it's original run on FOX); and "Leonard Betts", chosen as the lead-out for Super Bowl XXXI, and, as a result, would subsequently be the highest-rated episode in the entire show's run. The series' previous Friday evening timeslot would be taken by showrunner Chris Carter's next series, Millennium, which would also debut in October 1996.

The fourth season of The X-Files would conclude in May 1997 with 24 episodes. Notable in regard to the season's conclusion would be the upcoming feature film; Specifically that its' main production and filming would begin immediately afterward, during the hiatus between the fourth and fifth seasons.

The following weapons were used in Season 4 of the television series The X-Files:

Pistols

SIG-Sauer P226

After carrying a Smith & Wesson 5906 in Season 3, FBI Special Agent Fox Mulder (David Duchovny) returns to carrying a SIG-Sauer P226 as his sidearm, which he carried in Season 2. Mulder would carry the P226 from Season 4 onwards. FBI Assistant Director Walter Skinner (Mitch Pileggi) is also seen at times with a SIG P226.

Special Agent Dana Scully (Gillian Anderson) draws what appears to be a SIG-Sauer P226 in "Home" (S4E02). The weapon has a hooked trigger guard unlike a P228 and the slide and barrel appear too long to be a P225.

SIG-Sauer P228

After carrying a Smith & Wesson 5906 in Season 3, FBI Special Agent Dana Scully (Gillian Anderson) returns to carrying a SIG-Sauer P228 as her sidearm, which she carried in Season 2. Scully would carry the P228 from Season 4 onwards, except for several episodes in Season 4 (as well as Season 5) when she used a SIG-Sauer P225 instead (see below). FBI Assistant Director Walter Skinner (Mitch Pileggi) also carries a P228. Alex Krycek (Nicholas Lea) is seen surrendering a SIG P228 with suppressor in "Tunguska" (S4E08). Other FBI and government agents on the show are also seen using P228s.

Note that many (but not all) appearances of the SIG P228 in Season 4 show the weapon being handled roughly or during stunts, indicating those P228s are likely the rubber stunt version. It is possible that during Seasons 4 and 5 (the latter especially) the P228 was used more for stunt work while the P225 (mentioned below) was used more for firing sequences.

SIG-Sauer P225

In several episodes in Season 4, Dana Scully used a SIG-Sauer P225 rather than the P228. This might have occurred because the show's armorer was unable to bring a live P228 on-set for those particular episodes/sequences (At times the weapons interchange during the same episode). Scully first used the P225 in "Home" (S4E02), and would be seen using the weapon in numerous interspersed episodes throughout Season 4 and Season 5. Assistant Director Walter Skinner (Mitch Pileggi) is also seen (albeit rarely) with a SIG P225.

Walther PPK

Fox Mulder carries a Walther PPK as a back-up weapon, carried in an ankle holster as first seen in Season 3. He is notably seen using it when he loses his SIG-Sauer P226 in "Paper Hearts" (S4E10).

Smith & Wesson 5906

Special Agent Dana Scully (Gillian Anderson) is seen wielding the Smith & Wesson 5906 handgun that she carries in Season 3 in the Season 4 premiere episode "Herrenvolk" (S4E01). Special Agent Fox Mulder (David Duchovny) and Assistant Director Walter Skinner (Mitch Pileggi) are also seen with their S&W 5906s from Season 3 in "Herrenvolk" (S4E01). These are the same weapons from the previous season, with their particular features - Rounded trigger guard, adjustable sights, and black (blued-steel) triggers and hammers. A Syndicate operative is briefly seen holstering a 5906, also in "Herrenvolk".

Standard M1911A1 pistols are seen occasionally throughout the series. Vietnam veteran Nathaniel Teager (Peter LaCroix) uses one with blued finish to assassinate several U.S. Army generals in "Unrequited" (S4E16). Asst. Director Skinner (Mitch Pileggi) also briefly uses a blued M1911A1 in "Zero Sum" (S4E21).

Makarov PM

In "Terma" (S4E09), a number of Russian guards are seen armed with what appear to be Makarov PM handguns. Several of these guards use these from horseback as they pursue Mulder as he escapes the Tunguska gulag.

Makarov PM - 9x18mm Makarov

CZ 75

Syndicate operative Scott Garrett AKA the 'Mustache Man' (Greg Michaels) uses a CZ 75 pistol in an attempt to shoot USAF Staff Sergeant Louis Frish (Tom O'Brien), a military witness, near the conclusion of "Tempus Fugit" (S4E17), repeated at the beginning of the following episode "Max" (S4E18).

Unknown Pistols

A suppressed stainless pistol (possibly a Smith & Wesson 5906) is used by the Gray-Haired Man (Morris Panych) in the season opener "Herrenvolk" (S4E01).

A gulag guard with an unknown pistol holstered in "Terma" (S4E09).

One of the gulag guards on horseback wields an unknown pistol in "Terma" (S4E09). The pistol appears to be too large for a Makarov PM, and the rather blocky, squared shape also suggests it isn't a Makarov. Based on the general shape and appearance, it is possibly a blue-steel Jericho 941.

Revolvers

Taurus Model 66

Various Taurus Model 66 revolvers appear occasionally throughout the earlier seasons of the series. INS Agent Conrad Lozano (Rubén Blades) carries a 4" barreled stainless Taurus Model 66 as his sidearm in "El Mundo Gira" (S4E11). Soledad Buente (Jose Yenque) is also seen wielding the revolver at one point. This is almost surely the same Taurus revolver which previously appeared in Season 3.

Smith & Wesson Model 10

During a dream sequence in "Paper Hearts" (S4E10), Fox Mulder retrieves and attempts to use his father's Smith & Wesson Model 10 revolver. This is the same revolver he attempted to use to save his sister Samantha from alien abduction as a child, seen briefly in a flashback in the Season 2 premiere episode "Little Green Men" (S2E01). This is fitting, as the dream in "Paper Hearts" is partly a retelling of Samantha's abduction.

Unknown Revolvers

Throughout the season, many characters use various revolvers. Few are seen very clearly.

Submachine Guns

Heckler & Koch MP5A3

Numerous Heckler & Koch MP5A3s are seen throughout the series. These are wielded by police tactical officers and government agents, as well as military and black-ops personnel. Special Agent Dana Scully (Gillian Anderson) notably uses a Heckler & Koch MP5A3 with Surefire 628 flashlight forearm during the FBI raid on the militia group in "Tunguska" (S4E08). Unlike in previous seasons of The X-Files, the MP5s are no longer fitted with flash hiders in Season 4.

Black-ops commandos aim their Heckler & Koch MP5A3s in "Max" (S4E18). Note these weapons appear to each have two mags coupled together.

Heckler & Koch MP5K (Mocked up Kimel AP-9)

What appear to be Heckler & Koch MP5Ks are seen used by government agents and military/black-ops personnel. In reality, these are not real MP5Ks; but rather mock-ups built on the bolt carrier and magazine well of a Kimel AP-9, because the armorers in British Columbia did not have genuine MP5Ks during the 1990s. The same guns have also appeared in the film Crying Freeman and the series M.A.N.T.I.S. and The Outer Limits. These weapons are notably seen wielded by ATF SRT agents in "The Field Where I Died" (S4E05) and FBI tactical agents in "Tunguska" (S4E08).

Rifles / Carbines

Colt Model 715 / Olympic Arms K4B (Mocked up as M16A1)

Due to the series' filming in Vancouver, British Columbia, Canada for the first five seasons, most of the M16-type rifles seen throughout this period were Colt Model 715s, or, more likely, the Olympic Arms K4B equivalent, which seems to be favored by the Canadian armorers. These weapons generally appeared in the hands of U.S. military personnel as an M16A2 stand-in. Members of the Church of the Seven Stars are briefly seen with these rifles in "The Field Where I Died" (S4E05). In "Tunguska" (S4E08), Militia gunmen and several FBI tactical agents are notably seen using these rifles fitted with A1 hand guards to pass for M16A1s. Apparently, the armorers had no genuine M16A1s to use when the episode was filmed.

Olympic Arms K4B (Note however, that Olympic Arms did not name their rifles with the 'K' designation until after the 1990s) with A2 handguards, heavy barrel and "Stowaway" pistol grip - 5.56x45mm. This rifle is very similar to the Colt Model 715, but is distinguished by the "Stowaway" pistol grip, a feature often found on Olympic Arms AR-15 rifles made in the 1990s. Rifles similar to this one are frequently seen in productions filmed in British Columbia.

An FBI agent cocks his Colt Model 715/Olympic Arms K4B rifle fitted with M16A1-style hand guards in "Tunguska" (S4E08). Barely visible on the receiver is the brass deflector, a feature not present on an M16A1.

Two militia gunmen hold their Colt 715s/K4Bs at the ready in "Tunguska" (S4E08).

A militia gunman works the action on his K4B rifle in "Tunguska" (S4E08). With his hand clear, one can clearly see the Olympic Arms 'Stowaway' pistol grip on this particular rifle.

The militia gunmen fire their rifles. Note that the rifle in front has an A1E1-style receiver and heavy A2-style barrel - This combined with the 'Stowaway' grip shown in the previous screencap clearly indicates that it's an Olympic Arms K4B mocked up to look like an M16A1.

A closer view of the M16's barrel in "Tunguska" (S4E08), showing that it is a heavy A2-style barrel, although the rifle is fitted with M16A1 hand guards and meant to pass for an M16A1. Also note that the rifle is missing the forward sling loop under the front sight for some reason (it may have broken off during a stunt).

A militia gunmen fires his 715/K4B in "Tunguska" (S4E08).

Colt Model 733 / Olympic Arms K3B 'Commando'

Several episodes in Season 4 feature appearances of Colt "Commando"-type carbines, usually in the hands of military personnel and SWAT officers. None are seen very closely, but they appear to be the same A1E1-receiver short barrel carbines (Likely shortened Olympic Arms K3B equivalents) seen throughout the first and second seasons.

Colt Model 733 'M16A2 Commando' - 5.56x45mm. This is a 'shorty' version of the Model 723 / 'M16A2 Carbine', with 11.5" barrel instead of the 723's 14.5" barrel(s). This particular weapon is configured much like those seen in the series (and indeed, like Canadian Colt ARs), with A1E1 upper receiver (forward assist and case deflector with A1 sights).

A short-barrel Colt Commando carbine is seen wielded by a black-ops soldier in "Musings of a Cigarette-Smoking Man" (S4E07).

XM177 (Mock-ups)

XM177-style carbines are seen used by military personnel and SWAT officers, notably FBI tactical agents conducting a raid in "Tunguska" (S4E08). These appear to be the same weapons from Season 3 - All of them seem to be mocked up from other various AR-15 carbines (some have SP1 upper receivers, others have A1-style, and still others have the A1E1 style), as per the norm with XM177s in the vast majority of films and television.

XM177E1 Carbine (AKA Colt Model 609) - 5.56x45mm

Norinco Type 84S 'Target'

Two Norinco Type 84S rifles are seen in the episode "Terma" (S4E09), used by guards at the Tunguska gulag (as an AK-74 stand-in). Both rifles appear to be 'Target' variants with long barrels - One has a full stock and the other has an underfolder stock (Norinco Type 84S-1). It is interesting that only two Russian soldiers were seen armed with AK rifles while the rest of the unit were armed with batons/clubs (though several of the guards are later seen with Makarov PM pistols). There is a possibility that there were not many AK rifles available in Vancouver during the mid-1990s, which could explain why only two gulag guards were armed with rifles while the others were armed with clubs.

Norinco Type 84S 'Target' Rifle with fixed stock - 5.56x45mm. Basically a standard Norinco Type 84S with a slightly longer barrel.

The Cigarette-Smoking Man's Rifles

The 'Cigarette-Smoking Man' is seen wielding three rifles during "Musings of a Cigarette-Smoking Man" (S4E07) - The first two in flashback sequences, and the final one in the present.

Remington 742

The first rifle used by the younger Cigarette-Smoking Man (Chris Owens) is a short-barreled semi-automatic Remington 742. The rifle has a 'take-down' type of folding stock, and is fitted with a brass catcher. He uses it to assassinate President John F. Kennedy.

Remington 760

The second rifle wielded by the younger Cigarette-Smoking Man (Chris Owens) is a pump-action Remington Model 760 fitted with a scope. He uses this rifle to assassinate Martin Luther King Jr.

Ruger Super Redhawk (mocked up to resemble the KAC Revolver Rifle)

The third rifle, used by the present-day Cigarette-Smoking Man (William B. Davis), is what appears to be a Knight's Armament Revolver Rifle. This rifle is actually a mock-up built on a Ruger Super Redhawk revolver that was fitted with a carbine length bull barrel, scope, bipod, and a black synthetic buttstock. The weapon was originally built by Felcan Enterprises for the film Another Stakeout, but would subsequently be re-used on countless other productions filmed in Vancouver, including The Sentinel, Supernatural and Psych, in addition to The X-Files. Since the real Knight's Revolver Rifle also used a Ruger Super Redhawk as a base gun, this method for creating the mockup approximated the production method for the original weapon.

Shotguns

Remington 870

Remington 870s are wielded by police officers and and government agents throughout the series. 870s are also seen rarely in the hands of black ops soldiers. Both standard variants and variants with mounted forend weaponlights are seen. Special Agent Fox Mulder (David Duchovny) notably uses a Remington 870 with Surefire forend flashlight during the FBI raid on the militia group in "Tunguska" (S4E08).

Ithaca 37 "Stakeout" (Custom)

A custom Ithaca 37 "Stakeout" with a chrome finish on the barrel and magazine tube and an MP5K style pump-grip is used by Syndicate assassin Scott Ostelhoff (Steve Makaj) in the season finale "Gethsemane" (S4E24). This gun can also be seen in several episodes of the television series Supernatural, Human Target, Painkiller Jane, and several other TV shows filmed in British Columbia.

M203 Grenade Launcher

Briefly seen in the hands of one of the black-ops recovery commandos in "Max" (S4E18) is what appears to be a Colt Carbine (possibly one of the aforementioned XM177 mockups) with an M203 grenade launcher mounted. It could also be a Cobray CM203 Launcher, or possibly even an airsoft weapon or other prop. Given the angle that the weapon is seen at (briefly, and mostly obscured by a solider being filmed from the rear) a more definitive ID is not possible.

Composite Pistol

In "Tempus Fugit" (S4E17) and "Max" (S4E18), Syndicate assassins use dual-barrel Composite Pistols. These seem to take considerably after the weapon featured in In the Line of Fire, but have a somewhat different physical look and color tone than the weapon from that film.

The 'Dark Man' (David Palffy) assembles the Composite Pistol in "Tempus Fugit" (S4E17). As shown, the overall aesthetic of the components bears a striking resemblance to the weapon from the film In the Line of Fire.
