The Carbine Rifle, also known as the M4 and M16, is a rifle featured in every GTA game since Grand Theft Auto III. It is useful in almost any situation, boasting accuracy, power and magazine capacity. Throughout the games, the models differ slightly, along with zoom capability, rate of fire, and power.
Design and Performance
GTA III's rendition resembles the Armalite AR-10. This version is an inaccurately modeled and exaggerated weapon, with an exceptionally high rate of fire and a 60 round magazine. It has higher damage than the AK-47, which is somewhat untrue as the M4/M16 fires a 5.56mm round and the AK-47 fires a higher caliber 7.62mm round.
Vice City's rifle is modeled after the Colt 733, but called M4 in-game (which is inaccurate as the M4 was not introduced until 1994). It appears to have an aftermarket crane stock. Originally, a beta assault rifle that resembled an M16A2 was meant to be in the game but was later replaced by the current model. The M16A2's model can still be found in the game files and can be seen in the intro cutscene.
San Andreas reuses the model from Vice City, again called M4 in-game (and again inaccurate). This version has a drastically lowered rate of fire that is unusual for the rifle, but is still highly effective as a weapon. It also has a 50-round STANAG magazine. In the mission Stowaway, a government agent is shown holding a camouflaged Colt M16A1. This however, is never available to use in-game.
Yet again the model is reused in Liberty City Stories and named M4. The only change since San Andreas is that the fire rate has been increased.
Vice City Stories features an M16A1, named Assault Rifle in-game. It uses the same model from the San Andreas mission Stowaway, sans the camoflague. Lance Vance mentions the M4 during a mission, which is an anachronism. It functions just as all previous renditions have.
GTA IV features an M4A1, titled "Carbine Rifle" in-game. This version is accurate both in timeline and overall features, including weapon specs such as rate of fire, magazine size, etc. Unlike previous iterations, the carry handle has been replaced with an picatinny rail with an aftermarket drum sight mounted to it. It has the longest range of any non-sniper weapon in the game. It has "Property Of Liberty City Arms" stamped where the magazine release is normally found, probably a reference to the "Property Of U.S. Govt" stamped on its real-life counterpart. Performance wise, the Carbine Rifle is stellar. Accuracy and fire rate are both high, along with damage. It is highly effective in close to mid range, with accuracy dropping off at long range. Accuracy is even higher when crouched, allowing the player to fire it fully automatic while being able to hit the target reliably. This is somewhat untrue as carbine rifles are shortened versions of already long rifles such as the AK-47, so the range from the M4A1 is not as far as the AK-47, but the M4A1 likely has better muzzle velocity despite lower caliber so range is in a somewhat accurate to real life.
GTA Chinatown's rendition is difficult to identify, but it it has a full stock and long barrel, and the triangular hand guard as seen on the HUD suggests it is a Colt M16A1. It has tremendous power, more akin to that of a machine gun, and it has a fifty round magazine, like the San Andreas incarnation.
GTA V's assault rifle appears to be a Colt M4A1 that has been modified (or can be modified) with a shorter barrel, retracting stock and scope. It is unknown how this gun performs yet.
Spoiler Warning:Plot and/or ending details are in the text which follows.
Bedford Point, Staunton Island - In the walled off area in the southeast part of the Liberty Tree Offices, where the mission Kingdom Come takes place. (Use the nearby Moonbeam, park it by the lowest part of the wall, climb the Moonbeam, and jump over the wall to access).

Grand Theft Auto IV
It can be purchased from the back-alley gun shops for $5,000 and each additional magazine will cost $100. It can be purchased from Little Jacob for $3,500 with each additional magazine costing $70. The Carbine Rifle can also be acquired from NOOSE Tactical Response Unit Officers, FIB Agents and certain LCPD Officers, specifically those who guard places of high security such as The Statue of Happiness.
Tudor - Can be found in a small loading dock area on the north side of the old Sprunk factory.
Tudor - Can be found atop the northern superstructure of the old rail bridge that spans the river which divides Tudor and the Acter Industrial Park.
In the Playstation 2 version of GTA III, the M16 has a green aiming cursor, but in the PC, Xbox and iOS versions of the game, the green cursor is replaced by a circle and a dot.
Strangely, the M4 in GTA IV has two reload animations. When Niko is standing while reloading, he will pull the charging handle, but when crouching while reloading, he takes "out" the magazine, puts "another" in and pulls the charging handle. There is no confirmed reason for why there are two reload animations, but it is speculated that it is for balancing reasons, as the player is much more effective while crouched. This oddity is also present on the AK-47.
In GTA IV, the bottom of the Carbine Rifle's magazine is stamped with the words "Stop Chillin Start Killin".[citation/verification needed]
