Editing Colt Canada C7 and C8 (section)

===C8SFW===
The [[Special forces|Special Forces]] Weapon (SFW) features a longer, {{convert|410|mm|1|adj=on}} barrel of a significantly heavier profile than the C8A1 and a Rail Adapter System (RAS) handguard. The SFW [[Direct impingement#Stoner bolt and carrier piston system|operating system]] is more copiously gassed when compared to the standard C8A1 to enhance reliability in the presence of heavy fouling or icing at the expense of moving the bolt and bolt carrier faster and harder against the accordingly adapted buffer assembly, resulting in a free recoil increase. It is designed to provide a fire support capability in carbine form. A sleeve, called the Simon Sleeve, is slipped over the end of the barrel and is retained by the [[muzzle brake|compensator]] and its crush washer. It is used to mount standard issued [[C7 Nella bayonet]], [[CAN bayonet 2000|CAN bayonet 2000/2005]] and [[M203A1]]s.<ref name="Maintenance Instructions: C7 family"/>

The front sight base is strengthened for mounting of the [[Heckler & Koch AG-C/EGLM]] grenade launcher. The mass, muzzle velocity and effective range are stated as {{convert|3.4|kg|abbr=on}}, {{convert|895|m/s|ft/s|0|abbr=on}} and {{convert|550|m|yd|0|abbr=on}}.<ref name="Maintenance Instructions: C7 family"/> The C8SFW is in service with the [[Forsvarets Spesialkommando|Norwegian Special Operations Forces]] as their standard rifle, as the more recently introduced [[HK416]] does not feature a "heavy profile barrel" as the C8SFW. The [[United Kingdom Special Forces]] (UKSF) adopted a C8SFW variant, under the designation "L119A1".  In 2014, the UKSF upgraded to the "L119A2", which features a custom Integrated Upper Receiver (IUR). The Royal Marines Commando have also began phase out the L85A2/L85A3 as their main rifle in favour of the L119.
