It did have a shock buff in it, it's gone now. The shock buffer appeared to be in new condition though, it did not visually appear to be damaged, worn or crushed in any way.

Everything else to me looked good. Ejector was solid on the rail, it has the short ejector and the face of the ejector is perpendicular to the rails of the gun, no slight bevel that you see on the longer ejectors. The extractor doesnt have much of a bend to it, it appeared almost streight but when the firing pin stop is in place it's also solid, not enough clocking to be visually noticable. The extractor also appears to be radiused on the bottom of the claw a tiny bit.

I tried to cycle empty brass through it after it was assembled but that didn't work too well so I pulled the firing pin just because and it cycled live ammo fine and seemed to eject around 4:00 - 5:00 oclock. I don't know if hand cycling compares to actually firing the gun or not. I'll report back when I get to fire the gun again, not until this weekend at the earliest.

Thanks for the trouble shooting tips.
