That's an broad generalization that may be misleading. Comments about ejection issues on RFC get attention only because they are exceptions. No one posts about problems they don't experience.Anschutz has struggled with ejection issues on both the 54 and 64 actions for many years and the struggles and comments from shooters are well documented in the Anschutz forum on Rimfirecentral.
For an exception to this, I've had over twenty various Anschutz rifles, 64 and 54 actions, repeaters and single shots, and have yet to experience an ejection problem.
