"Medium to long range assault rifle, takes 5.56mm caliber ammunition."
— In-game description

The C8-SFW is an assault rifle featured in Tom Clancy's Rainbow Six Siege. It was introduced in the Operation Black Ice expansion pack and is available for use by the Operator Buck. As a weapon exclusive to its Operator, the weapon comes with an irremovable under-barrel shotgun by default.[1]


The Colt Model 725 (or the C8 carbine) is a carbine variant of the C7 assault rifle. It is a carbine assault rifle manufactured by Colt Canada that chambers the 5.56×45mm NATO round. The C8 is smiliar to the American M4 carbine (The C8 has ambidexterous fire selectors). The C8-SFW (Special Forces Weapon) variant has a special 400 mm (15.7 inch) barrel that differs from the other variants of the rifle.

In-game, the C8-SFW is, to put simply, a fast and powerful assault rifle with a rather challenging recoil. The high vertical recoil makes long range engagements rather difficult, especially compared to other assault rifles, due to its inability to equip a Vertical Grip.

The C8's mostly vertical recoil pattern makes the Flash Hider and Muzzle Brake both excellent options for stablizing early-spray recoil. The Compensator is not very effective since there isn't much horizontal recoil for it to mitigate.

Under Barrel





  • Kills with the Skeleton Key underbarrel do not count towards any gadget challenges in the Weekly Challenge System, only shotgun challenges.
  • The model used in-game is not actually a C8SFW rifle but in reality a C8CQB variant with a M4 RIS.
  • In the Season 1 Pro League Weapon Skin FAQ promotional image, the the C8-SFW is equipped with the vertical grip attachment, even though it's not an available option in game. In the same image, the M590A1 shotgun also has an angled grip equipped, which is also not an available option.[2]
