I have no experience with their firearms, but like CE, I love their replacement parts.
They work great & they are my "go to" parts for Ruger semi-auto rimfire replacement parts.
Matter of fact, one of the first things that I do when I buy a Ruger rimfire is chunk the factory extractor and install the Volquetsen replacement.

If their guns are like their parts, they ought to be pretty good.
