I find myself in a unique position to be able to review 4 6.5 grendel uppers.
The first one is the Larue Ultimate Upper kit. For about $800 shipped you get everything you need minus a stripped lower. This kit also includes the Larue trigger of your choice. Their triggers are SUPERB.
This is the upper that stands above the others. The machining is beautiful, the throat is clean and the rifling looks clean and crisp. For the price this is my first pick now.
The other three are all similar in machining. The throats are a little “crunchy looking “ but everything is functional. These include PSA, Grendel Hunter, and SOLGW.
I was really hoping the SOLGW or the GH would show a bigger difference from the PSA. In the end I would buy PSA if I wanted to save a couple bucks but really I would probably just get the Larue.
