the normal G7 has the same thread as all older angels.
the thread was changed with the G7FLY and 06Speed, then changed again for the A1.
its a common mis-conception- most people just call the newer style threads 'Angel 06 threads' as its actually only two different markers that have this thread, the G7FLY and the 06 Speed. then obviously 'a1 thread' for A1 barrels.
