Steyr LG110 Match shroud removal

[DaveAnkers]

Hi, I use a scope on my LG110 Match, and would like to remove the shroud in order to move the balance aft. I have removed the two grub screws and have tried to remove it by hand, but it is too tight on the barrel. Anyone know how it was fitted? Heated and shrunk? Loctite? I do not want to damage anything and so would like to know how it was fitted before going any further and possibly returning it to Harry Preston for him to do and ensure the warranty remains intact.
When the shroud has been removed, I am thinking the best thing to do is have it shortened so it is just long enough to protect the barrel crown.
I have thought of fitting a silencer, but I shoot ten metre acoustic, and no baffling is allowed under ISSF rules.
Thanks in advance
