I have they are great people there and I have ordered from them a few times. Most of my AR-15 and M4 upper parts are from them and I have never had any trouble with them.
I had to send the upper back because I did not like the railed handgaurd that ran along the top of the recever so I sent it back with the YHM free floating handgurd and it was fixed out sent back to me with no trouble and gave me credit (I quickly spent that) on the lower cost of the YHM one. I talked on the phone with them are there very nice and take time with you. I recomend them to everyone that wants AR parts.
