I have a POF piston upper I am breaking in, I was using no lube (mistake) when it got hot the bolt would stick closed with no round in the chamber, I had to hold the CH and hit the stock on the ground, does this sound like a lube issue?

It could be from lack of lube. How many rounds had you put through it without it?

sounds like bolt is seized in the carrier.   take it apart and look for gauling.

Doesn't POF claim that their uppers don't need lube?

Only when it is hot, no marks , scrapes or gouging, I cleaned it and lubed it, it is hand cycling smooth, and the problem was intermitent

while pof advertises that it will run with no lube, I have found that milspec dry lub tw25b works the best.  It is an alchohol based lube so it goes on wet and then dries.  Try it out, I use it because it makes the ease of cleaning the bcg just as easy as using no lube, but with the added insurance of using lube.  Best of luck.  And if you order of the site, buy $50 dollars worth of stuff so you get free shipping.
