I have a relatively old Colt AR-15 A2 sporter HBAR, Is the flash hider removable on it? what would the threads most likely be ?

Yes. 1/2x28

Put the upper in a upper receiver action block, drop it in a vise and use a armours wrench to take off the FH. It also has a the old school peel washer on it.
