To be honest, they never took pics of the delivered fixed stock version either, yet we know it's real and most folks who ordered already got theirs to play with. Until there's proof of the contrary, the leading theory should be that the folders are also real and delivered to TI's warehouse, waiting to be shipped (or hopefully already being shipped, as TI said).
As for the BRS-99, go for it... you won't be disappointed. It's an extremely nice and impressive piece, made with German-like quality and attention to detail. The bonus is that any fellow Canadian gun owner you show it to will be probably more excited to see it than even a T81 (because the BRS is such an unusual and unique firearm to see unharassed under our draconian and asinine gun laws).
Again, TI may not be the most efficient operations-wise, but they do get the cool stuff in... while other dealers are content to bring in just another $3000 AR platform that's been beat to death a thousand times over and pretend it's "big news". TI has a lot of balls for doing what they do and take a lot of risk doing it, money-wise. I respect them for that... even though the T81 folders wait has indeed been a b*tch!
