The following weapons were used in the film Top Shot:
The Beretta 92FS is used for the voting challenge in every episode.
Episode 2: "Zipline of Fire" had a focus on the Beretta 92FS, and it was featured in every challenge.
Beretta 92FS Inox
The Beretta 92FS Inox is shown with a suppressor in the opening credits.
Single Action Army
Several Single Action Army's are seen in the opening scene. In Episode 6: "Wild, Wild West", Single Action Army revolvers are seen where they are called "Peacemaker"s.
Smith & Wesson Schofield
Used in Episode 7: "Trick Shot Showdown".
Tressitu TZ-99
A Tressitu TZ-99 is shown shooting in slow motion during the opening scene. This handgun is also used in Episode 4: "Friend or Foe?", for the elimination challenge. In the challenge it is described by Colby as "a TZ99: a South African made 9mm handgun."
The Beretta Xtrema 2 is used in the Elimination challenge in the latest episode, trick shot challenge, to shoot clay pigeons.
Rifles
Sharps Rifle
A Sharps rifle is seen in Episode 2: "Zipline of Fire" laying while the sun passes over it.
Colt Model 715 "AR-15"
The Colt Model 715 "AR-15" was used in the fourth episode, "Friend or Foe", during the team challenge.
The gun they're using has an A2 sight so it's not a 715, it's likely a Colt AR-15A2 or possibly a military M16A2. The CGI model is an M16A4 though, note the removable carry handle. - Gunmaster45
A M1903 Springfield is used during the first challenge in the first episode when the teams were shooting explosive reactive targets at 50 and 100 yards.
Mosin Nagant Rifle
A Mosin Nagant Rifle is used along with the Springfield during the first challenge in the first episode.
Tokarev SVT-40
A Tokarev SVT-40 is used along with the Sprigfield, the Mosin Nagant and the M14 during the first challenge.
M14
A M14 is used along with the Spingfield, the Mosin Nagant and the SVT-40 during the first challenge. This is most likely just a civilian M1A instead of the fully automatic M14.
Remington 700
The Remington 700P is utilized by Mike and Kelly during the first elimination challenge where they had to shoot explosive reactive targets at 200, 400 and 600 yards.
Unknown Lever Actions
Several unknown lever action rifles (among others) are shown on gun racks throughout the series.
Would guess the two lever guns are Henry 1860's and a Sharps rifle on the bottom. Gunner313
