about 3mm proud of the spring would be usual for a top hat. Doesn't have to be that long about 12- 15 mm overall.
Make sure that spring will still compress without the top hat touching the guide. This is normally done by assembling the rifle with no spring, cocking the gun and making sure the sear engages correctly.
Thanks for the info Neil, that’ll certainly be useful , sounds like i won’t have to take anything off the spring which will be handy !
