Texal:
Just punch the pins out is the main thing. Details in the stickys.
BUT: the only difference between extractor and ejectors is the height of the catch plate.
There's a spur sticking up. NEF ground/filed one down for me for $24 with some extra parts and had to send them the barrel too.
You can do this with a file real easy. Just keep it straight and take it down to .420" instead of the ejectors .460"+.
You don't need to take the belly out of them like Trotter explained in the sticky's.
