They test fire each upper with 3 rnds of wolf. It would be easy to machine mount them and test fire the uppers. The ones that shoot the best get culled for further testing with good ammo. If they shoot sub MOA they then charge more for the upper.
It cost nothing more than time and a bit more ammo.
I have a BCA Grendel that shoots sub MOA, while others have gotten junk.
