You can buy a Russian sks blued for 200-350$ some more but 200-300$ and then you get the Yugo or a new Chinese sks 700$ or more ! Any better quality ? Nope more desirable ? Not to most, but some fellas like them.
So far without proof, or unbiased side by side review and or extensive round count on both the 180c and 180b we will not know the real differences are there. So until then my guess is the 180b won’t sell very many if any at all and the 180c bring half the price will continue to sell tons.
I’m happy we have a multitude of feedom stick options
