Brocock Bantam reflex moderator

I just bought a like new Brocock Bantam with the reflex moderator on it. I love the gun but sure would like to quiet it down a bit more. How is the reflex installed on the shroud? Appears to be glued but not sure. I just assumed it was screwed on but it wont budge

If it's like the Regal Reflex (I would think it should) the end of your shroud should be threaded 1/2-20 and the Reflex should be screw on to that. If you got it from AOA then they likely used thread locker.
