Dunno that I’d call Russian parts “bootleg”. “COUNTERFEIT” is a far more accurate descriptor.
Who knows how the QA/QC on these parts will go? If Chinese counterfeit parts and their flawed metallurgy are an indicator, it’s caveat emptor for any who use 'em. I have absolutely no doubt these things will show up on the black markets of Asia, Africa, and South America, nor that they’ll find their way into the N. American and European supply chains. It’s a simple matter to create a fraudulent paper trail.
