Long story short...few years ago I had an AMD63 built from a parts kits. I took it to the range and had some failure to feeds so I took it home and put it in my safe and it has sat there since. I am now back playing with it and noticed some wear on the ejector and was wondering if this is normal. Thanks!

it is not normal and it would be wise to (try to) determine the cause, as it may be a symptom of something else.
For rewelding, I use stainless weld on (theoretically) hardened parts, with a copper heat sink clamped underneath to prevent burn-through. And this is TIG work unless you are a freaking master with a MIG. The ejector should align with the slot in the bolt. I prefer contact minus a few thou. Not as critical on a 7.62, but on a 5.45 it is (smaller case diameter). Problem with measuring an ejector comes from the importance of its relationship to center-line, not so much protrusion from the wall. On receivers with sloppy center-support rivet spacers, a bow in or out can negate the "proper" protrusion. |
