Is my CETME Flash Hider pinned? I wanted to change it out for a PWS91 flash hider (if the gun works out) but the sticky only mentions the Century brake being pinned. I really don't want to try and unscrew it if it's pinned and bugger up the threads.
Thanks (in advance) for your responses, guys.
Edit: Wow. Stumped the experts? Perhaps you need a pic of my FH before you can tell me? How can I tell where the pin is without taking a grinder around the whole FH or is there no other way?
