This product is garbage - Aero Precision AR-15 Magpul MOE Lower Parts Kit w/No FCG

I ordered this product for a lower build I put together. First issue is that it was missing front/rear take down pin spring. I did not realize this until I was almost done with the lower build. I was frustrated but just ordered another one to save the hassle of a return. Once the weapon was put together I did a test fire of 15 rounds and noticed the weapon was not firing correctly. I opened the weapon to find the buffer retainer pin had broken off. Upon further inspection, the metal is garbage and definitely not milspec as advertised. Had to order another one of those as well. Very frustrating. I'm tempted to scrap the whole lower parts and order from someone who has quality control. Cannot stress enough how trashy this product is.
