After a cursory attempt to assemble my bolt, and giving up due to extremely tight tolerances on the ejector pin, I took my parts to a gunsmith here in town.
Twenty minutes later, the ejector pin was broken. He managed to machine down an m16 pin to fit, mostly. He said it should last a few thousand rounds but it does not insert all the way. I honestly don't know what to do now. This is a master gunsmith of 25 years experience, and I know I'm at least the second person this has happened to.
Despite North Sylva's work to make this right, I believe that the stripped left hand bolts on the market should be recalled, sent back to Israel for reassembly, then redistributed. As it stands, I do not believe them to be fit for consumer use.
