RCMP has declared the Sterling Arms R9 MK1 carbine a prohibited firearm, effective July 6, 2025. This sudden reclassification impacts all models, including sub-models 198846-1 and 198846-2.Canadian Shooting Sports Association (CSSA) alerted its members, warning the move is a major blow to owners. Effective immediately, using the R9 MK1 at ranges or for hunting is illegal. Owners must now follow strict rules for storing and transporting the firearm. Selling or transferring it is also banned, with very few exceptions..CSSA stated this is another tough hit for responsible shooters who used the R9 MK1 for competitions, training, and recreation. CSSA is monitoring the situation but expressed uncertainty. It is unclear if the federal Liberal government will include this firearm in its gun grab.CSSA said this prohibition raises wider concerns. Adding firearms like the R9 MK1 suggests previous government cost estimates for buying back prohibited guns may be far too low. .The total taxpayer cost could potentially reach billions, similar to past programmes like the long gun registry, the CSSA warned. It urged transparency on the financial impact.Affected gun owners must comply with the new legal requirements immediately. The CSSA advises consulting the official RCMP Firearms Reference Table or contacting a local firearms officer for guidance.
