Your experience mirrors mine with one I did several years ago. Helped friend put upper together, applied the blue Lt, and he went on his merry way. Only to discover later his chamber wasn't correct so it had to come apart and go back to the manufacture. It took a big freaking hammer to get it apart and heat was applied prior to attempt. It did not just come right out after one to two smacks with the hammer. It was an ARP barrel which was the cause of some drama, oh I digress, lol.
These days I prefer to assemble without blt and test drive for mostly function, then if no issues surface break it down and do whatever mod's to it and reassemble.
