I appreciate all the help. After reading everyones posts I definately have too much of a gap between the BCG and buffer. This was my first 308 build and I did not realize they were not MILSPEC like the AR15s. The POF lower must me just a hair different than the DPMS upper. I am going to machine a plug simmilar to the CWS recommended that will take up the 1/32 gap as see what happens. If I keep it light it should noy upset the timing. This is the third issue I have had with the POF lower....not sure I would go that route again. May ebd up with a DPMS lower if I cant make it work.
