Not Good So Far...

I just recieved this set and its not good. The castle nut will not unscrew off the buffer. Either the threads are bad on buffer or castle nut is bad. I was able to unscrew the nut 2 rotations but it's taking off all th finish in buffer and will not go any further. Maybe I got a bad one which happpens... I emailed Primary Arms so will update this review once I have some form of resolution. Hopefully they help make this right. It appears others had success with this product so I'm hopping this is "one off". I was super excited as PA got my order out ASAP even with holidays. BUT this is the last component of my lattest build and not I have to wait:(.
