I'm an idiot, for some reason I was thinking the op had cycling issues.

The first thing I'd be looking at for light primer strikes is the hammer spring. A common problem is having it installed backwards.

You might want to take along a second AR. If trouble persists you could swap uppers to determine whether it's a light hammer or something in the upper.
The biggest issue with assembling an AR isn't so much getting the parts together right - it's getting the right parts together.
