You could have a look on youtube Airarms S200 anti tamper removal, probably wants a bit more heat. Rog

Thanks for replying, I've gone through you tube and my eyes can't take any more just don't seem to be able to find anything regarding the tool needed ,if I apply any more heat it'll melt . The thread lock melted with the little pug of smoke and she still tight, I've even tried drilling but this isn't happening in the slightest I've done 4mk1and mi2 but never with the anti tampering issues help
