The Canadian Armed Forces are set to adopt variants of Colt Canada’s MRR as the Canadian Modular Assault Rifle (CMAR). The announcement stated that up to 65,000 rifles may be procured over the next 5 years to replace the Colt Canada C7 rifles and C8 carbines currently in Canadian service.
According to the Canadian government, the contract will be for the procurement of up to 65,402 weapons: 16,195 will be the Canadian Armed Forces’ Full Spectrum (FS) variant, and the remaining 49,207 will be the General Service (GS) variant.

The FS variant is designed for front-line combat roles and will be optimised for ‘offensive operations in urban and open terrain’, and is described as having ‘advanced features’, likely optics and a suppressor, these will be issued to Regular Infantry units. The GS variant is intended for broader use across the Canadian Armed Forces (CAF), with the Canadian Army stating that it will provide “reliable personal protection and deterrence for personnel who are not in primary combat roles.” This seems similar to how the U.S. Army plans to deploy its new NGSW weapons to close combat forces and how the U.S. Marine Corps issues its M27 rifles and M4 carbines.
The exact configuration and barrel lengths of both variants have not been confirmed, but both rifles have monolithic upper receivers, carbine-length gas systems, ambidextrous controls, MLOK forearms, are chambered in 5.56x45mm and while barrel lengths have not been announced they are likely to be a 14.5in barrel, perhaps alongside a 20in variant, with an approximate weight of 3.4kg.

Variants of the CMAR have been in testing for some time, with variants initially designated the C8A4. In January 2024, it was reported that the first 500 ‘basic C8A4s’ had been assembled and supplied to the CAF for “final user input” on configurations. These have been seen in photos of trials with troops since mid-2024. Colt Canada’s MRR, or Modular Rail Rifle, was first unveiled in 2015. Last year, at SHOT Show 2025, I had the chance to take a look at the latest configuration of the MRR: the MRAR – Modular Rail Ambidextrous Rifle.
Over the last 18 months, a number of photographs have been released featuring Canadian troops training and trialling CMAR variants in various configurations, including with a SAI Optics 6 patrol scope and a 5.56 Huxwrx suppressor. Other configurations tested appear to have included carbines with optics from SIG Sauer, Burris and Steiner.

The promotional video released with the CMAR procurement announcement, however, features a carbine with a C8A3-marked lower receiver, a Strategic Services MFMD suppressor and a SAI 6 optic in FDE. These were displayed by Colt Canada at DSEI 2025. It remains to be seen if this is the final configuration of the CMAR variants are both equipped with the same optics and suppressors. In terms of what the final designation for the rifles may be, a clue appears to have been offered by a pair of photos shared by the Department of National Defence’s LinkedIn page, feature a carbine with a longer barrel which appears to have a lower receiver marked ‘C25’, suggesting this is a potential designation for the CMAR rifles.

The CMAR project will be delivered through 2 phases:
Phase 1 includes procuring 30,000 General Service (GS) rifles over three years. The estimated value of this initial phase is approximately CA$307 million, including applicable taxes.
Phase 2, which is expected to begin in year four under an optional provision, will include procuring the remaining 19,207 GS rifles, 16,195 Full Spectrum (FS) rifles, as well as associated ancillaries.
The two-phase approach spreads the cost and prioritises the replacement of the C7.

The Canadian government was also keen to highlight the economic drivers of the sole source contract award, noting: “The investment will bolster Canada’s defence industrial base for years to come, creating good‑paying jobs and contributing roughly $10 million annually to Canada’s GDP over the next five years.” The announcement added that Colt Canada has a commitment to include at least 80% Canadian content on the weapons.

The Canadian Army expects that the first deliveries are expected in 2027. It remains to be seen what the final configurations of the two variants will be and what their final designations might be.
