Great product, missing parts - Tdi Arms AK M4 Stock Adapter For Yugo M70, NPAP & OPAP - Full Kit

It installed on my M70 Yugo just fine other then the missing castle nut. Clearly someone at the warehouse took it out of the sealed bag needing that part. Had to go to a local gun store to get the part to finish the install. I was told it will take 2-3 days to hear from optic planet's customer service reps about the missing parts. I am Not happy with them right now and its ridiculous it left their hands clearly it being opened. Good news it was a cheap part.
