I ordered an AR striped Lower and build kit and had it shipped to my FFL dealer. after registering it and picking up I took it home to start building. After all of the pins were installed, I noticed that the lower was missing the hole for the buffer tube retainer spring & Pin. It had never been machined into the lower. I contacted PSA for a warranty return and started the claim. I had to remove the newly installed pins and springs to ship it back. After shipping it back, PSA decided to replace the lower due to it was out of spec. I asked if PSA would pay the charges to get the warranty replacement registered and they refused. I asked for a store credit to cover the cost I paid to register the defective lower and they refused. I asked for a new lower pin kit, a $12 kit and they refused. I do not feel that this is the right way to treat a customer who purchased and registered a PSA defective part. I understand that mistakes happen but PSA needs to always take care of your customers and make things right when it was a quality control issue on PSA’s end, not mine.
