5 minute operation provided you have Imperial hex keys.
Pull action from stock
Remove rear trigger group screw
Remove 2 rear breech screws (hold on to pressure tube cap #42, spring pressure!)
No need to degas (If you want to degas, remove #25 bolt stud from hammer, pull spring and hammer, use a rod of sorts to push on valve stem to release air out valve)
See what was used to plug hole in pressure tube cap ( id. is threaded) remove obstruction
Assemble in reverse
Find a good tune
Now rifle is FAC unless valve or transfer port are restricted
