The TRs 301 is a 5.56mm assault rifle appearing in S.T.A.L.K.E.R.: Shadow of Chernobyl, S.T.A.L.K.E.R.: Clear Sky, and S.T.A.L.K.E.R.: Call of Pripyat.

Appearances[]

Shadow of Chernobyl[]

A light rifle with an effective fire range of up to 300 meters. Due its to[sic] exceptionally easy triggering, high ergonomics and low weight, the weapon is highly accurate, though it is too sensitive to dirt and is not always suitable for use under difficult field conditions.
Shadow of Chernobyl in-game description

The TRs 301 is one of the first 5.56mm weapons the Marked One will come across, easily found within the Wild Territory, as it is used by most Mercenaries in the area. It suffers from mediocre reliability, but has terrific accuracy, reasonable stopping power, and is very lightweight. It can also mount all three types of attachment (a scope, silencer and grenade launcher), making it fairly versatile.

It is a decent weapon to use in the early parts of the game due to its good overall stats, with its low reliability as the main drawback.

Acquisition[]

In Shadow of Chernobyl, the weapon is the primary weapon of most experienced Freedom members, Veteran Loners and Monolith members. It is also widely used by the Mercenaries. It is also quite easy to obtain one in top condition from zombies in Yantar (it seems that zombies drop weapons in ideal condition much more often than regular stalkers).

The TRs 301 is sold by Skinflint, and Barkeep will reward the player with one for completing the mission Find artifact Goldfish. Four rifles can be found inside the Freedom armory in the Army Warehouses.

Unique variants[]

  • Sniper TRs 301 – a unique version made by the Mercenaries, sporting an integrated silencer, and strangely, a custom x1 SUSAT scope, at the cost of significantly reduced firing rate. The weapon does not suffer from the 20% stat penalty caused by a mounted silencer and is noticeably more durable than the stock model.

Clear Sky[]

A new step in the development of the famous M-16 family. Thanks to an exceptionally smooth release, good ergonomics and satisfactory weight, this rifle facilitates high firing accuracy. However, it is prone to catching dirt, which may lower its effectiveness in field conditions. Uses 5.56x45 mm ammo.
― In-game description

The weapon can mount a SUSAT scope and silencer without any upgrades, however a modification is needed for it to mount an under-barrel M203 grenade launcher. It is inexpensive to maintain, and uses the same upgrades as most 5.56mm class assault rifles. It tends to jam more than most rifles, but is still a good deal more reliable than the IL 86. Firing the weapon in 3 shot bursts or in single shot will reduce the rate it is damaged firing compared to it being fired on full-auto all the time. Overall, due to poor reliability it loses with Eastern weaponry available at the moment when the player will first encounter the TRs 301.

Acquisition[]

In Clear Sky, this weapon is often employed by Freedom members, experienced Loners, veteran loners, and is in abundant use by the mercenaries. It is sold by Ashot, and occasionally Shilov and Tooth, though it's so widespread that one may be easily salvaged.

It can be found in the following stashes:

Unique variants[]

  • TPs "Left-hander" - a unique variant that was cut from the final release of the game. It is described as a successor to the Shadow of Chernobyl Sniper TRs 301.
  • Hermit sells a variant of this weapon with pre-installed upgrades that change its caliber to 5.45x39mm, increase its accuracy and reduces its rate of fire.
  • A unique TRs 301 was meant to be available in Major Zvyagintsev's shooting range. As with the other shooting range guns, it can only fire in semi-automatic mode and comes with various pre-installed upgrades that improve the weapon's damage and accuracy but reduce its rate of fire and bullet speed.

Call of Pripyat[]

A new step in the development of this famous weapon family. The changes were made to the upper half of the steel construction comprising the barrel, gas tube and bolt assembly, reducing the weapon's weight, improving ergonomics and its gas system. The weapon is highly accurate, although its propensity to catch dirt makes it a poor choice for the Zone's difficult conditions.

Trs-301 upgraded all

Upgrade view

Its rate of fire is higher than most other rifles, the accuracy is better than the IL 86, and the handling is on par with the Viper 5. It also weighs less than most other assault rifles, and is one of the three assault rifles that can accept a scope, silencer, and grenade launcher by default (the others being Strelok's SGI-5k and the Storm), making this weapon one of the most versatile weapons overall. However, due to Strelok's SGI being an unique weapon available in stashes and the Storm being expensive to obtain, the TRs 301 is a great counterpart to use in the early game.

It can even surpasses the SGI-5k in term of damage per second due to its rate of fire, but it has some drawbacks – it has low durability without upgrades, which rapidly deteriorates its accuracy and recoil. In fact, out of all weapons in the game it is the most affected by wear, and it has the lowest durability of any assault rifle.

Keeping it in top condition is a must as once its durability is reduced by 1/4, it will start to jam very frequently and often in the most inconvenient of times such as during a heated firefight. Durability damage rate can be lessened by firing the weapon in single shots or in bursts of 3.

Overall, the TRs' reliability is still better than in Clear Sky and not much worse than other weapons and thanks to many advantages of using this weapon, it may serve as the player's main weapon, until they manage to get a higher-end weapon.

The TRs 301 has a large amount of upgrades. The mag capacity can be upgraded to 40 rounds, and the weapon has a fair amount of fire rate, accuracy, flatness and reliability upgrades, making the weapon more powerful, easier to use and more useful at long range.

Acquisition[]

The TRs 301 is used almost exclusively by experienced Loners, Monolith and Mercenaries operating throughout the Zone, making it fairly easy to obtain one early on. Some Freedom members, mostly Experienced, make use of the TRs alongside the IL 86. It is commonly carried with an attached scope and/or silencer.

The TRs 301 is sold by Owl once the player achieves friendly reputation with the Loners, and by Hawaiian by default.

It can be found in the following locations:

  • Zaton - at the very north of the swamps (north of the lake), hidden in some bushes, along with 120 5.56x45mm SS109 bullets and 4 M209 grenades. Coordinates given by Gonta if the player directly reports Flint to him.
  • Zaton - under one of the houses in the Izumrudnoye village, along with 120 5.56x45 SS109 bullets and a bandage. Coordinates given by Spartacus if the player sides with the Loners in The Hit.
  • Jupiter - under a red metal transport crate in the Northwestern tunnel, along with 240 5.56x45 bullets. The player must take care as there is a Tesla anomaly roaming about there with many Electro anomalies assisting to it. Retrieving the rifle itself is difficult as it is beneath the container, forcing the player to crouch to recover it, while paying attention to the roaming Tesla.
  • Jupiter - under a tree on the right side of the entrance to the same tunnel, along with 180 5.56x45 bullets, Martha with 100 9x19mm FMJ bullets, few medkits and bandages (coordinates given by Trapper after completing Hunting: Unidentified Mutants).
  • Jupiter - under a damaged molo, north-west to the Plavni anomaly, along with 240 5.56x45 bullets and a medkit (coordinates given by Trapper after completing Hunting: Kill the Swamp Bloodsuckers).
  • Jupiter - behind the armory of the Volkhov AA Complex, along with 120 5.56x45 bullets and two RGD-5 grenades.

Trivia[]

  • The weapon in-game ejects casings through a closed dust cover. This makes no sense, as all AR-15 derivatives feature a spring-loaded dust cover, which will slam open when the bolt is locked, and stay open until manually closed. Note that not all AR-15s have a dust cover or a forward assist, this simply depends on the version or manufacturer.
    • Additionally, the dust cover locks open once the charging handle is pulled, and must be manually closed after firing. However, the rifle's dust cover in-game closes automatically after cocking.
    • The weapon in Shadow of Chernobyl is also missing the bolt, as seen when reloading.
  • In early builds, the TRs' forward assist had a complete pull animation when it was reloaded. In all games however, it's always static.
  • In all three games, the TRs 301 has misaligned iron sights (the gun would shoot higher than where the sights are). The aperture sight is in fact not used, and it's worth noting that the aperture sight itself is opaque, rendering it unusable.
  • In all three games, mounting a SUSAT scope on the TRs 301 does not remove its iron sights, which would make the use of a scope quite impractical as they would obstruct the view.
