Swipe on brass

It’s a maxim bolt I bought from Lilja with the barrel. Should the outter edge of the ejector be slightly rounded or squared off ? Thanks

Over the years I've been playing with ARs most ejectors I've seen have a small radius. Some were flat-faced & some had a sort of a truncated cone shape. As I said, a large majority have the small radius. I've put my own radius on those that were flat-faced. Squared off ejectors will definitely cut into your cartridge rims. I remember seeing a You Tube video where the presenter ground a bevel on the side of the ejector nearest the cartridge rim to cure a feeding problem he was having.
