That's fine that the delay may be the fault of the RCMP, but NEA shouldn't be promoting this sort of gun coming if there is a risk a a six-month delay.
A better course of action would be to wait for the RCMP non-restricted approval and THEN post the upcoming specs about the rifle while you build a ton.
Then in the month it takes you to build the first run of 1,000, the Canadian internet frenzy happens, and when the buzz is at its culminating point you launch them for sale.
That's how you win marketing.
You lose marketing by showing your audience something that's coming "soon", and then don't deliver for 6+ months. It doesn't matter if it's your fault or not.
