The handguards are also unique as the threads are different on the upper. I had some issues with the lower interfering with the bolt stop preventing the bolt from sliding freely. Cadex sorted it out for me at no charge. Feel free to pm me if you want to chat about it. Great rifles once its done. Love mine.
