It's actually a decent firearm. It'll shoot NATO rounds as well as .223 rem, it's a piston gun so it runs cooler and cleaner than a DGI. It takes standard pmags and it's quite reliable.
A VFG does make it an AOW, but you can put a magpul AFG on it without violating any laws or paying any taxes.
Is it a "go to war" gun? probably not, but as a fun shooter and even a defensive weapon it's fine. Like any short barreled 5.56, it's loud as hell, so for HD I'd suggest a can and/or active hearing protection.
