the Noveske I had, was a MOA on most occasions with most loads after they replaced the first barrel...good people... Dogzapper bought one of those Gunsight carbines with 14.5 inch Noveske M249 barrel and he indicated to me that it was a MOA or better barrel.
I expect Noveske sells good barrels on my experience and DZ's, no personal experience with a spikes or PSA.
