Actually not terrible, what killed me is my MIG is acting junky I was going to try and fix the old one. The metal in this gun seems to be heat treated through and through which makes it hard and brittle. Not a bad thing in a lot of ways (resists peening) but the grain size on the broken sear and the extractor seemed to be crystalized through and through. Taking the actual breech plug apart was hard, and even that was probably 20-30 minutes of real work.
