They are fine - approaching days of yore (pre 64). I have a next-to-new 77 just purchased that also has the re-improved machined internals (and a return to better external receiver metal) and it is fine. Not sure when they changed back to the better metals and production processes but it was before mine. Keep it, enjoy it. Jury's out on whether to actually shoot it at your late date (approaching the end of the top eject run). I'm with those wondering about a scope on these: I say don't even think of putting a scope on a top eject, enjoy it for what it is which in non-scope form is about where the basic goodness of the gun is anyway (no AE flames please, those are great too for the scope option they do offer). I say shoot it and enjoy it and pass it on down to the next generation in whatever form it is by then, unless it is virtually new = safe gun.
