So the upper receiver is off. Did you install the barrel yourself?
He said the rifle upper would not function on the pistol lower either... The lower seems to be the common denominator.

Do you have any pics of the lower with the upper removed so the FCG and buffer are visible?
Edit: check to make sure the buffer retention spring is low enough to allow the bolt to clear.
You may also be able to shave a blonde hair off the top of the buffer retaining pin, but that is a very fine line and easy to take too much..
I think I am going to try this and if i screw it up I do have another lower parts kit.
As stated in my OP this was my first build and know nothing about the internals of AR's but I actually thought that endplate was thick looking.
Here goes nothing!
Good suggestion! I'd try that first, only takes a few secs..Why not try swapping the buffer retainer pin with a known good one first,before you go dremeling things?
