There is simply nothing holding the flash hider in, no screws of any sort that I can make out which was why I'm thinking it was glued on. Thanks for all the suggestions, will try ripping it off in pieces but failing that, I will try the hot blow dryer. Will consider the torch as a last resort next to the big rock, I have a creme brulee torch which "should" be less damaging.
"Hey I'm the first one to say its a great country but its a straaaaange culture. This is a place where gun store owners are given a list of stolen credit cards but not a list of CRIMINALS and MANIACS. And now they're thinking of banning toy guns...AND THEY'RE GONNA KEEP THE F**KING REAL ONES!"
