Correction! The C9 LMG is made by FN, not Colt Canada. Derp.
Colt Canada, formerly Diemaco, has made a limited number of their monolithic uppers available to Canadian civilian shooters. I picked up one of their “blemished” units back in October and have had a great time shooting it.
These upper receivers that came to the civilian market were overrun from a military contract, possibly with the Danish Army. They were sold without charging handles or bolt carrier groups, but did feature a 15.7″ cold hammer forged barrel and a C9 flash-hider.
The IUR is part of the C7/C8 upgrade program and offers a free floated barrel and rock solid handguard for mounting accessories and optics. We did see a new M-LOK version called the MRR at Shot Show 2016. Complete versions of the Modular Railed Rifle are expected to be available to Canadian civilian shooters this summer.
