Hey y'all first time poster here.I did a quick search to see if I could find an answer to my question, but did not notice anything. I have been in the process of assembling my first ar-10. I have assembled an ar-15 prior to this. I purchased a Wilson Combat receiver set and have already noticed some issues. First the pivot and takedown pins (CMMG) were too large in diameter and will not fit, Wilson Combat says "buy from us". Now I have run into an issue with the barrel. I purchased a Faxon Match series heavy fluted 18". The barrel will not seat into the Wilson Combat receiver. Using a set of calipers it seems there is a 0.65mm difference in diameter. I have tried to check for compatibility before I purchase and ensure that everything I have is DPMS styled and have even seen posts of Faxon barrels with Wilson Combat receivers. Did I purchase a Wilson Combat lemon? Or does Wilson Combat manufacture their receivers to only be compatible with their parts? I appreciate any help/advice y'all can provide, thanks.
