I have one and it's a good upper except that the gas port on my Satern Liberty 18" barrel is huge (.093") which resulted in ejection issues with Hornady (but not Wolf) ammo because my action cycled insanely fast. I finally tamed it with a variety of tweaks: reshaped extractor lip, heavier buffer and an adjustable gas block were the big ones. To his credit, the builder Andy pressed me several times to send it back for him to diagnose and correct but I like to work on them so I did it all myself.
I also think that the Maxim bolt I purchased with it was to blame for occasional light strikes (interior FP channel catching the FP) and I recommend an Alexander hard use bolt instead. I added a 7.62x39 enhanced FP (slightly longer) to eliminate light strikes and it did for 98% of them.
But Andy stands behind his rifles and he'll take care of any issues that crop up.
