One might even compare it to theMinigun or the M-60 seen in later games. The GTA III version of the rifle differs from any other variant for how powerful it is: Featuring an exceptionally high rate of fire and an unrealistic 60 round magazine, it is always a one shot kill against any enemy in any part of the body and can easily destroy most vehicles with a few bursts, making it arguably the most powerful firearm in the game. The weapon has a 60 round magazine, even though the one modeled in-game looks like a regular 30-round AR magazine. This is a rather odd choice, since the AR-10 is a considerably old rifle who was mostly in service in European countries (Such as Germany, Portugal and Italy) during the 50s and the 60s, and is therefore considerably hard to find in America.
GTA III's rendition has considerably lower quality than its successors, apparently resembling the Armalite AR-10, judging by the handguard and the overall shape. The Carbine Rifle (also known as M16) is an assault rifle that has been featured in every GTA game since Grand Theft Auto III.
