Stargate SG-1 - Season 8
The following weapons were used in the eighth season of the television series Stargate SG-1:
The most common sidearm seen in used by the SG teams (although in real life, the M9 is the military designation for the Beretta, the prop weapons used in the show are most likely the civilian Beretta 92FS).
(Mock-up) Beretta M93R
Machine pistols with the appearance of Beretta 93Rs are seen in a number of episodes being used by US Secret Service agents, and the Trust agent Hoskins. If you look closely, you can see that they have the slide-mounted safety/de-cocker switch, whereas the 93R has it mounted on the frame. That means they're actually Beretta 92FS dressed up to resemble M93Rs (with fake forward grips and flash hiders) and probably converted to auto with drop-in units; identical guns have also appeared in Harsh Realm and I, Robot (which were both done by the same armourers who worked on this show).
Smith & Wesson Model 10
Dressed up Taurus PT99AF AKA Timecop gun
Seen in the episode "Icon" (Season 8, Episode 5) and used by the main villain at the end, this pistol is in actuality a Taurus PT99AF. This prop was later seen in Stargate Atlantis as the standard sidearm of the Genii people. This prop pistol was originally produced for the movie Timecop.
FN P90 Personal Defence Weapon
Primary weapon of SG-1 through the Season.
Heckler & Koch MP5A3
The Heckler & Koch MP5A3, almost exclusively equipped with the Surefire dedicated forend weaponlight, is the primary weapon used by all SG teams for the first few seasons. Then when the main cast and some supporting and extras switched to the P90, the MP5 became less common. Also seen in use by the Free Jaffa Nation later in the series. MP5 also makes a small comeback when we see them again in the hands of a special assault unit raiding a Trust compound. Throughout the series it is generally the case that for non firing scenes the actors carry airsoft replica MP5s with a Navy trigger group, whereas for firing scenes their weapons switch to real firearms with SEF trigger groups.
Seen at the end of the episode "Icon" (Season 8, Episode 5) in the hands of religious fanatics and their leader Soren (James Kidnie).
Cobray Street Sweeper
First seen used by Brigadier General Jack O'Neill (Richard Dean Anderson) in "Reckoning: Part 2" (Season 8, Episode 17).
One of the SWAT men in "Full Alert" (Season 8, Episode 14) holds a Remington 870 with black synthetic foregrip and buttstock.
Seen being used by SG-3 in "Zero Hour" (Season 8, Episode 4). What's interesting to note is that while most of the other SG teams use submachine guns, SG-3 is armed with an M82, M16, M16 with M203, and an M60. They are a USMC section tasked with SAR, retrieval and Tactical Support ops. They pretty much come out to play when extra firepower is needed or another team got into a situation that they can't handle.
Diemaco C7/Olympic K4B
Seen used by Marines, and the security of Stargate Command. These are all Olympic Arms K4B rifles (same receiver style as the Colt Model 715/Diemaco C7), standing in for the M16A2.
Some of the SFs at Stargate command can be seen with what appear to be genuine M16A2s, as noted by their adjustable rear sight. It is possible that thjese are replicas used only in non firing scenes, being substituted for Olympic Arms K4B rifles when actual blank firing is required.
GAU-5/A and GAU-5A/A
The GAU-5/A and GAU-5A/A were the USAF contract versions of the XM177 and XM177E2 "CAR-15" short assault rifle. The USAF Security forces used them until recently, however, most of the non firing GAU-5A/As seen in the show were simply XM177E2 "Airsoft guns". The actual GAU-5A/A carbines look like the XM177E2 but don't have forward Assist buttons. The GAU-5 variants that appeared on the show seem to be a mix of full-auto converted Colt AR-15 SP1s and Olympic Arms K3Bs, all with chopped barrels and fake GAU-5 flash hiders installed. The converted AR-15 SP1s have the "slab-side" receiver, while the K3Bs are recognizable by their 715-style receiver (forward assist, brass deflector, A1-style rear sight) and "Stowaway" pistol grips.
Hudson Model Gun AKS-47
Russian soldiers in "Full Alert" (Season 8, Episode 14) can be seen carrying Hudson Model Gun AKS-47 as stand ins for the real AKS-47.
In the episode "Icon" (Season 8, Episode 5), both the human factions on the alien world uses these rifles along with their AKs. It was seen in the hands of security guards and soldiers. Daniel (Michael Shanks) also held one at the end of the episode.
Mauser Karabiner 98k
Mauser Karabiner 98k rifles were commonly seen in the episode "Icon" (Season 8, Episode 5) alongside other firearms, such as the Garand, the AK, the PPSh41 etc.
Usually seen carried by the Cheyenne Mountain guards in stock footage.
One of the primary weapons utilized by the Stargate teams. During later seasons they are rarely seen without any attachments, mostly being equipped with flashlights, Cobray flare launchers and laser aiming modules. A small side note for the interested reader: The lower handguard on the M4 has to be removed in order to accommodate underbarrel grenade launchers like the M203 or, in this case, the Cobray 37mm Launcher.
Seen used by guards in "Icon" (Season 8, Episode 5) and "Full Alert" (Season 8, Episode 14) used by Russian soldiers. These appear to be Norinco Type 84 rifles modified with a Krinkov parts kit to resemble the actual AKS-74U, a practice not uncommon in movies and television shows
Remington 700 Choate Super Sniper Stock
When the Air Force personell search the Trust's warehouse in "Affinity", one can be seen carrying a bolt action rifle, which is a suppressed Remington 700 in a Choate Super Sniper Stock. This weapon, like many others, was supplied by Tom Felcan, a Vancouver based company, who appear to use this firearm in a lot of the productions they are brought in for.
Government soldiers and zealots in "Icon" (Season 8, Episode 5) can be seen wielding Zastava M70.
These two guns were set up in the gate room but were never used in the 10 years the show ran for. The M2 was also used at the Alpha site in "Allegiance" (Season 6, Episode 9), but was - once again - not fired. The weapon was then seen in "Bad Guys" (Season 10, Episode 16), mounted on an APC used by the alien security forces. The only instance were the weapon saw actual combat was in "Forever in a Day" (Season 3, Episode 10), were it was mounted on a F.R.E.D. during the onslaught of Heru'ur´s Jaffa.
Daewoo K3 (mocked up as M249)
Contrary to popular belief, there are no real FN Minimi or M249 light machine guns used in Stargate: SG1 or its sister show, Stargate: Atlantis. The light machine guns used by the SG teams are actually Korean-made Daewoo K3s that have been fitted with M249 Paratrooper-style stocks and shortened barrels. Some of the K3s seen on the show also have RIS rails and vertical grips similar to those seen on the Mk 46 Mod 0.
M60 Series GPMG
Seen used by Marines in a support role in several episodes and the movie Stargate: The Ark Of Truth. Some marines are carrying the M60E3 version.
Cobray CM203 Flare Launcher
Seen attached to M4s and M16s. Prop wise, these were all Cobray 37mm flare launchers meant to mimic the appearance of an M203. What tips them off is the absence of a second trigger, the shape of the trigger guard, the lack of a step up in the receiver, and the cocking lever on the SIDE of the receiver.
