They are very high quality lowers and the Gen 2 lowers have some nice additions. Functionally? About the same as most others but they do have a very nice fit and finish (of the ones I've seen) and are really not that much more expensive (if at all) than other "high end" lowers. A Gen 2 chainsaw (blemished) lower has been on my short list of builds as an RLL host, but until the panic dies down that train has set sail. I've got some other noveske parts (barrel, rail, etc.) and everything I have seen from them has been top notch.
I think blem Gen 1's prior to all this were like 149 and Billet Blem Gen 2 were 240 or so? and maybe 199 and 299 non-blem As I recall on Ranier Arms about a month ago.
