My IRG order for the 14" 5.56mm rifle totalled $2310 with the factory Buttstock and GST, which works out to $2882 CAD at today's exchange rate. North Sylva is quoting $2799 for the 11" and $2999 for the 16.5", so say $2899 for the 14" (if NS were carrying that miitary barrel length). So right in the same pricing ballpark whether you order through IRG or NS, assuming one or the other has the exact Bren 2 MS configurattion that you are looking for. The 7.62x39mm guns are in short supply, apparently due to sales to Ukraine. The 5.56mm firearms appear to be in good suppy however.
I for one, am just pleased (and relieved) that IRG can bring in the 14" Barrel with the Bayonet Lug for the correct military configuration as used alongside the 11" carbine by the Czech Army.
