I watched Ava's video this morning before she hid it. Apparently she broke the embargo by accident.
I don't have any screencaps for you, but it's basically a significantly improved SUB2k. Instead of folding up, it folds to the side, so it's friendly to optics. Although, I don't understand just why the rail is not on the receiver, but on the handguard only. The charging handle is non-reciprocating. The bolt release does not work as a release, which I think is a mistake.
Overall, FPC looks quite decent. Not my cup of tea, but should be a good option of those considering SUB2000 or perhaps Cx4.
P.S. BTW it's the second product-improved KelTec that S&W made recently, the other is a clone of KSG. S&W RFB when.
