After a couple months hiatus, I finally got to the range. I had tried a new 6.5 Grendel on my Colt lower and it didn't work. Not sure if it was the fault of the upper, the lower, or the magazines. In any event, I bought a new PSA lower to finish out the Grendel. This morning I tore down the Grendel upper to check on the gas system. I think the gas block was clocked a bit rather than perfectly aligning with the port in the barrel. Fixed that and put it all back together. So I put a magazine through the reassembled Colt just to make sure all was in order, then function tested the Grendel. All seemed to work as it should. A couple of misfeeds with one particular magazine, so that may need some attention. The others worked fine.
