Yes, it is CCW thread. I've tried to unscrew it using pliers, but didn't move it at all. and yeah- the flash hider has this tiny screw on the rear that releases it before you are able to unscrew it, but I've didn't noticed anything on the big part behind it that I need to remove in order to put the suppressor on the outer barrel- green rectangle on this picture:

The part in the red rectangle in the picture I've posted. I thought the flash hider is only the small part in front of it I want to to put the silencer on the thread that sticks right after the rail

@mightyjebus I've just got my hands on my replica. I want to get a dummy silencer, but I'm not sure how to get off the gas block/ outer barrel. I figured out how to remove the flash hider, but the other part is not moving at all. Maybe there is a screw somewhere that fixes it, can you help me?
