Editing Colt Canada C7 and C8 (section)

===IUR – Integrated Upper Receiver===
In 2008 or 2009, Colt Canada introduced a completely new designed upper receiver with integrated rail attachment system.<ref name="Colt Canada Corporation"/> The front handguard is in this system permanently attached to the upper receiver. The whole system is forged from one piece, and is sometimes called a monolithic rail. This system allows for a completely free floating barrel. Another unique feature is that the system can be adapted for different barrel lengths by screwing on an extension.

The system was introduced as an upgrade in the Dutch Army with the C7 and C8 in 2009.<ref>{{cite web|title=Brochure Colt Canada 2010|url=http://www.coltcanada.com/pdf/CC-2010-brochure-rev20120417.pdf|archive-url=https://web.archive.org/web/20121030005128/http://www.coltcanada.com/pdf/CC-2010-brochure-rev20120417.pdf|url-status=dead|archive-date=October 30, 2012|year=2010}}</ref><ref>{{cite web |url=http://avrm.wordpress.com/category/defensie-ministerie-van-defensie/bewapening/diemaco-c7c8-5/ |language=nl |title=Algemene Vereniging van Reserve Militairen |access-date=January 31, 2013 |url-status=dead |archive-url=https://web.archive.org/web/20140325211341/http://avrm.wordpress.com/category/defensie-ministerie-van-defensie/bewapening/diemaco-c7c8-5/ |archive-date=March 25, 2014 }}</ref>
In 2010, the C8 IUR (Integrated Upper Receiver) was introduced as an upgrade by all four branches of the [[Danish Defence|Danish military]] and the [[Danish Security and Intelligence Service]]'s [[Politiets Aktionsstyrke|SWAT]] teams, as the "Gevær M/10".<ref>{{cite web|url=http://www2.forsvaret.dk/viden-om/materiel/udrustning/vaaben/gevaerer/Pages/Gevaerer2.aspx|title=Geværer|access-date=2015-02-14|archive-url=https://web.archive.org/web/20150214073350/http://www2.forsvaret.dk/viden-om/materiel/udrustning/vaaben/gevaerer/Pages/Gevaerer2.aspx|archive-date=2015-02-14|url-status=dead}}</ref>
