Just to clear things up... The Evo is indeed designed in Denmark, manufactured in Denmark and assembled in Denmark. A number of small components are imported in, like bolts and shims. I've assembled one myself.
The CZ 805 BREN is made for ASG exclusively by King Arms. This is no secret.
The BREN was originally slated for release prior to the Evo, but the project was delayed, leading to the Evo coming through to the market first. If you would like to put "Evo Internals" in a BREN, I would recommend using the 2018 Evo cylinder set and an ASCU V3 Gen. 5 with hop unit and empty mag detection.
ASG openly use manufacturing partners to produce exclusive, licensed products. The Evo is the first in-house manufactured product but ASG are in the process of designing and prototyping the next in-house manufactured, licensed RIF.
