Also, the color of the magazine, rail cover, pistol grip, stock, and sights are all in the Flat Dark Earth (FDE) color instead of straight black. The M16 is not available in-game out of the box but you can reconfigure the M4A1 to look and fire like most M16 versions once you unlock the attachments necessary. Unlike the more modern versions of the M16, the M4A1 was designed to shoot semi-auto and fully-auto. Burst fire is a standard fire mode on the M16 but it can be unlocked and used if desired. As the M16 did, the M4A1 is also chambered in 5.56x45mm NATO with a 30 round magazine setting the standard for NATO STANAG assault rifles.This is a very long post talking about the realistic weapons of Rainbow 6 Siege. If close attention to detail or accurate portrayal of weaponry does not matter to you, you need not read this post. Rainbow 6 Siege has always had a good relationship with it's realism from Day 1. From the outset it has always tried to convince you it was realistic whenever possible. Gadgets were grounded in reality, guns were all real and for the most part used by who uses them. Even when the game needed to be balanced a certain way they found a way to make sure the visuals fit this game balance. Defenders get weaker weapon damage overall both because of game design demanding it, but they also use weaker weapons - SMG's firing pistol caliber rounds, while the attackers using harder hitting weapons use large caliber rounds. The balance decision was not arbitrary - the reason for why defenders do less damage was self evidence and explained in game through a real life explanation.

Headshots don't kill you because the game design said so it's because getting shot in the head with a bullet, be it a pistol or rifle round, is going to kill you. There are many more examples to point to but all these various little details added up. This showed a certain level of passion and respect for the source material. The base game had a few standouts, like the FMG-9.
