During the SFW trials, the C8 outperformed both the [[Heckler & Koch G36]] and the [[SIG SG551]].<ref>{{cite book|title=Vickers Guide: AR-15, Volume 2|author1=Larry Vickers|author2=James Rupley|publisher=Mott Lake Publishing |year=2017|page=82}}</ref><ref>{{Cite web|url=https://www.forgottenweapons.com/uk-special-forces-m16-variant-the-l119a1/|title=UK Special Forces' M16 Variant: the L119A1|first=Ian|last=McCollum|date=January 21, 2022|website=www.forgottenweapons.com}}</ref> The C8SFW was subsequently adopted in 2000 under the designation, L119A1.

Use of the C8 has expanded to include, among others, the original [[Special Air Service|SAS]] and [[Special Boat Service|SBS]], the [[Special Forces Support Group]], the Pathfinder Platoon of [[16 Air Assault Brigade]],<ref>{{cite web |title=Pathfinders lead the way for airborne forces |url=https://www.army.mod.uk/news-and-events/news/2018/04/pathfinders-lead-the-way-for-airborne-forces/ |website=British Army |access-date=15 March 2023 |date=26 April 2018}}</ref> [[Royal Military Police]] Close Protection teams<ref>{{cite web |author1=Ministry of Defence |author-link=Ministry of Defence (United Kingdom) |title=Royal Military Police train for close protection |url=http://www.mod.uk/DefenceInternet/DefenceNews/TrainingAndAdventure/RoyalMilitaryPoliceTrainForCloseProtection.htm |website=Ministry of Defence |date=7 August 2012 |archive-url=https://web.archive.org/web/20121109162528/http://www.mod.uk/DefenceInternet/DefenceNews/TrainingAndAdventure/RoyalMilitaryPoliceTrainForCloseProtection.htm |archive-date=9 November 2012|url-status=dead}}</ref> and [[Ministry of Defence Police#Armament|MoD Police]].<ref>{{cite web |author1=Ministry of Defence Police |title=Freedom of Information request - Ministry of Defence Police:Duties |url=https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/498753/20160202_REDACTED_Reply_eCase_00790_RFI_2416_Re_MDP_Duties.pdf |access-date=15 March 2023 |date=2 February 2016 |id=Ref: FOI2016/00790}}</ref><ref>{{cite web |author1=Ministry of Defence Police |title=Freedom of Information request - Ministry of Defence Police:Weapons |url=https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/390675/MDP_Weapons_Redacted.pdf |access-date=15 March 2023 |date=19 December 2014 |id=Ref: FOI2014}}</ref> Most weapons are now fitted with Knights Armaments Rail Adapter System handguards (that hold zero on the top and the bottom rails) and Picatinny rail flat-top upper receivers. The muzzle velocity and effective range are stated as {{convert|895|m/s|ft/s|0|abbr=on}} and {{convert|550|m|yd|0|abbr=on}} with a 400&nbsp;mm (15.7") barrel and {{convert|790|m/s|ft/s|0|abbr=on}} and {{convert|250|m|yd|0|abbr=on}} with a 254&nbsp;mm (10.0") CQB barrel.<ref name="Maintenance Instructions: C7 family"/>

Most users fit Trijicon [[Advanced Combat Optical Gunsight|ACOG 4×32]] sights with CQB reflex attachment, but other sights are used. Various lasers, lights, foregrips and other attachments are used. Surefire 4-prong flash hiders are generally fitted, and suppressors are available. The standard Canadian bayonet is issued but rarely used. Coloured furniture is becoming commonplace. The United Kingdom prefers polymer magazines to metal ones on grounds of weight and reliability and has now standardised on these for all C8 and operational [[SA80]] users, with well over a million magazines purchased. Many weapons are fitted with the [[Heckler & Koch AG-C/EGLM|L17A1]] underslung 40&nbsp;mm grenade launcher (UGL), the UK designation for the [[Heckler & Koch AG-C/EGLM]]. Detachable shoulder stocks are available for stand-alone use of the UGL.

[[43 Commando Fleet Protection Group Royal Marines|43 Commando Fleet Protection Group]] replaced their L85A2 rifles with the C8 in 2016.<ref>{{cite news |last1=Ripley |first1=Tim |title=UK Royal Marine unit ditches the SA80 for Colt C8 |url=http://www.janes.com/article/58501/uk-royal-marine-unit-ditches-the-sa80-for-colt-c8 |work=Jane's Defence Weekly |date=3 March 2016 |archive-url=https://web.archive.org/web/20160317184342/http://www.janes.com/article/58501/uk-royal-marine-unit-ditches-the-sa80-for-colt-c8 |archive-date=17 March 2016|url-status=dead}}</ref> In 2019, ''[[The Times]]'' reported that the C8 would become the standard-issue rifle of the [[Royal Marines]] replacing the [[SA80]].<ref name="Times2019"/><ref>{{Cite news | url=https://www.naval-technology.com/news/industry-news/royal-navy-limits-commitment-to-littoral-strike-ship-development/ | title=Royal Navy limits commitment to Littoral Strike Ship development| newspaper=Naval Technology| date=7 November 2019| last1=Lye| first1=Harry}}</ref>

In July 2013, the British Ministry of Defence contracted Colt Canada for a £2.8 million mid-life upgrade of the L119A1 carbines used by the United Kingdom Special Forces. Subsequently, from 2014 the L119A1 was upgraded to the L119A2.<ref>{{Cite web|url=https://www.forgottenweapons.com/l119a2-the-new-british-sof-rifle/|title=L119A2: The New British SOF Rifle|first=Ian|last=McCollum|date=January 24, 2022|website=www.forgottenweapons.com}}</ref><ref>{{cite web |title=Fleet Upgrades, Licensed Programs & Custom Builds |url=https://www.coltcanada.com/fleet-upgrades-licensed-programs-custom-builds/ |website=Colt Canada |access-date=15 March 2023}}</ref> There are two L119A2 variants: The standard Carbine with a {{convert|400|mm|1|abbr=on}} barrel and CQB (Close Quarter Battle) with a {{convert|254|mm|1|abbr=on}} barrel. The CQB variant has seen the most widespread use. Both L119A2 variants feature a custom integrated upper receiver (IUR) with rails that hold zero all around, a lighter profile barrel, straight [[Gas-operated reloading|gas tube]]s, Geissele trigger, [[SureFire]] 4-prong flash hider, a tan coloured Magpul 6 position collapsible CRT buttstock, Ergo pistol grip, and ambidextrous controls.
