I just traded for an slr-95.Havent shot it yet but it was filthy,powder caked on gas tube.It looks like a really well made milled ak.It has a thumbhole stock,which it digging in my grip.I hate it. I believe Im going to keep this one.What can you tell me about these and what I would need to do to legally change out that thumbhole stock. I know nothing bout them. Wanna kill these ads? We can help!
