Looking for first hand with a Shernic Gun Works sks Bullpup

How are these? Any problems? The gun im looking at is a norinco professionally cut and crowned to 17" with sgw kit. Never had a sks, but wanted one of these bullpups for a while. Please share your pros and cons as well as experiences please. Thank you.

The trigger linkage isn't great, but overall it makes for a very fun to shoot gun.
