Swiss Arms/Famae question.

[Bowie]

What parts will interchange between the PE-90 and 540-1? Trigger groups, bolts, bolt carrier, extractors?
Thanks

55x charging handles interchange into a 54x, 54x charging handle may work in a 55x but has clearance issues.
Receiver pins interchange.
Pistol grips interchange.
Trigger guards and triggers alone interchange, fire control group is different however.
5.56 top rails interchange.
