I have owned an NEA product (CQB Carbine with PDW Suttstock) that ran for the most part once I installed an adjustable Gas Block, but suffice it to say that the firearm had issues. I didn't touch anything created by the re-branded BCL, as they were just NEA with a name-change. Now I understand that they are under new management with improved Customer Service. The real question however, is whether the products have also improved to the point that they function well, are aesthetically pleasing, and are therefore actually worth buying.
I am not adverse to giving BCL another try now that they are under new management, but first I am going to have to hear from my fellow CGNers who know about such things that the designs make mechanical sense and that the machining is properly done. Based soley on that criteria, things don't sound all that promising for the current iteration of the Siberian. Of course much can change between the prototype or toolroom model and final production specifications. I get that, and hope that the Siberian will see positive chane between now and production status. If for one do like and appreciate the fact that the Siberian has a much more compact and sleek profile than the AR180B-based competition. I am keen to take a peek inside, although I think I already have a pretty good idea of what's going on. Perhaps "SIG MCX" inspired??
