No,, I do not think the entire production is just for the FoNRA. It's actually very possible that they are not making any at the moment. They do NOT have a dedicated manufacturing line to handle ALL of their models all the time. They build a batch,, re-set the line & make a different model. It MIGHT be that they haven't made any lately & they are awaiting enough orders to re-set a line to make the next batch.
And apparently,, by some of the posts above,, there are some of them available in other places.
Also,, smaller gun shops OFTEN can not get their distributors to sell them a hot item. The distributor salesmen will take care of bigger clients first. Throw in an "allocation" of a number of guns for a distributor,, and it can be very frustrating to try & get a specific model that's in higher demand.
