Rise of the Tomb Raider
The following weapons appear in the video game Rise of the Tomb Raider:
Lara finds a Nagant M1910 revolver in the Train Yard level. Concept art shows it as break-action, though in the final game it has a correct swing-out cylinder. Oddly, it also retain the non-working front hinge of a Smith & Wesson break-action revolver from the earlier version. Nadia, a NPC appearing in the Baba Yaga DLC, draws her Nagant on Lara after being found hiding in a locker. Lara quickly points out that the revolver is empty, and Nadia admits that the firing pin is broken anyways. It can be upgraded with a speed loader for faster reloads.
Remington Model 1911 R1 Enhanced
The Remington Model 1911 R1 Enhanced pistol is used by both Lara Croft and Trinity soldiers as the "Semi-Auto Pistol". A special version with a matte black finish, the "Accipiter Nox", is available with the Siberian Ranger DLC. While in Syria and during QTEs the weapon has unlimited spare ammo, in normal play it requires Lara to find ammunition. Unlocking the Hollow Point skill allows Lara to craft hollow-point rounds for increased damage. The stock 7 round magazine can be extended to 10, 14, and finally ??? rounds. Fired with Mouse Button 4, the HP rounds can be fired without reloading, resulting in Lara firing over 83 rounds (75 HP + 7 round base mag size) without reloading!
IMI Desert Eagle Mark XIX
The "Heavy Pistol" and "Moon Shadow" are roughly based on the Desert Eagle Mark XIX.
A revolver of unknown make appears in the game as the "Venom Hand Cannon".
The Beretta 92SB is used by Lord Richard Croft in a flashback to commit suicide. The model appears to have been recycled from the 2013 game.
Heckler & Koch USP Match
The Heckler & Koch USP Match appears as the weapon icon for the Desert Eagle, presumably in reference to Lara's preferred weapon in the original post-2001 continuity.
Heckler & Koch MP7 Prototype
A modified Heckler & Koch MP7, based on the 2nd Heckler & Koch PDW prototype, appears as the "Submachine gun", a high rate of fire, low damage weapon available after Lara finds all 4 parts for it. For some reason, the grip is slanted rather that straight. The foregrip is always folded up and a unusable dot sight is mounted.
Type 100 submachine gun
When Lara first enters the Geothermal Valley level, Remnant fighters are seen with Type 100 submachine guns fitted with home-made grenade launchers during a cutscene. The Type 100 is seen again in the hands of Trinity soldiers as they advance to the Chamber of Souls. The model is recycled from the previous game, and the weapons are never seen again, with both factions using the WASR-2 in-game.
Winchester Model 1912
Lara acquires a Winchester Model 1912 shotgun during a battle in the Geothermal Valley's Upper Village after Jacob disarms a Trinity soldier of it and tosses it to her. Initially a stockless Trench version, the bayonet lug and heat shield disappear after Lara gets the weapon. Trinity Breacher-type mercenaries use the cutscene Trench version late game as well. The model used by NPCs is recycled from the previous game whereas Lara's is a new model made for the game.
12 Gauge Double Barreled Shotgun
A 12 Gauge Double Barreled Shotgun is available as the "Break-Action Shotgun" after Lara finds the parts for it. While powerful, its usefulness is diminished by being the third shotgun available, as the Tactical Shotgun can be bought early game and the Pump Shotgun is acquired before all the Break-action's parts are found. An even more powerful Gold version, Thunderclap, is awarded for achieving 100% completion and a short-barrel version, Voidhammer, is available with the Cold Darkness DLC.
A Franchi PA8 with a vent-rib barrel, most of a Franchi SPAS-12 foregrip, a top rail on the receiver, and Benelli-style ghost ring sights appears as the "Tactical Shotgun" and can be bought at the Supply Shack for 140 Byzantine Coins. It can be fitted with all the same upgrades as the Winchester Model 1912, as well as a 12-shot drum magazine for quick reloads.
The Izhmash KS-K shotgun appears as the "Full-Auto Shotgun", and it unique version "Harbinger" with a red paint job. It is fitted with an after-market handguard and an enlarged charging handle. The 6-round magazine can be upgraded to a 12-round box magazine and then a 15-round drum.
The Remington 700 appears as the "Bolt Action Rifle" in game. There is also a gold variant of it available known as "Goldenfang".
The WASR-2 is the standard weapon of all factions, including Trinity and the Remnant. Lara aquires one after disarming a Trinity solder in the Gulag level, and it is avalable the rest of the game. Oddly, the gas tube is not present on the weapon, the game treating it as a Tier 4 upgrade that increases the rate of fire.
The WASR-2 can be upgraded with extended 35 and 40 round magazine, an AMD-65 style heat shield, AK-74 style muzzle brake, and an extended barrel, resulting in a mish-mash of various AK-47 derivatives. The end result resembles the Zastava M72.
Heckler & Koch G36K
The Heckler & Koch G36K appears as the "Military Rifle" and is used by Trinity Enforcers, often with laser sights. Lara can buy it from the Supply Shack for 140 Byzantine coins. The stock 30-round magzine can be upgraded to a 45-round box magazine and then a 60-round drum. A snow-camo version, Snowflake, is available.
The M203A1 appears as the "Rifle Grenade Launcher" and is available for 120 Byzantine Coins at the Supply Shack. It seems to be based on a G&P airsoft model due to the simple RIS mount. The trigger guard and trigger are missing on the in-game model despite being visible in the Supply Shack. Fired with MB4, the M203A1 is fitted to all Rifle-category weapons and does not need to be reloaded as long as Lara has ammo for it. Despite this, trying to fire without ammo will result in Lara attempting to reload.
Home Made Grenade Launcher
The grenade launcher from the 2013 game returns, mounted on Type 100 submachine guns used by Remnant fighters and Trinity mercenaries in cutscenes.
Various Trinity solders, known as Fireflies, are armed with flamethrowers to make Lara's life miserable. In proper video game fashion, the operator can only be killed by shooting the tanks until they explode
Type 1 Heavy Machine Gun
M67 hand grenade
A M67 hand grenade is thrown at Lara in a cutscene.
Trinity soldiers throw smoke grenades at Lara in a cutscene.
Frag grenade (M203 Airsoft)
Lara finds what appears to be a modified Airsoft version of a M203 40x46mm round in a Remnant arms cache and uses them to craft Grenade Arrows.
