Because it is a brand new upper, you may be experiencing some problems due to minor flaws in the metal work... You might try working the charging handle for an extended period of time and then lube things up a little to see if that helps...
If the problem is short stroking, I think you will likely need to have the gas port opened slightly and then use an adjustable gas system to alloy you to adjust the gasses for the specific load you want to use.
Another move done by many people is to relocate the gas port to the pistol location to allow for a longer gas pressure period but that is a more complicated mod...
I hope that someone else will post to share their experiences but the above is the general fixes that I have seen done over the years and these solutions seem to work for most people.
