I've known this dealer for years and I've bought many weapons from him but I've never had a problem with any gun I've bought from him. This is however the first gun that wasn't right out of the box. He bought the saiga NIB and did the conversion, not tuned, just converted. Nothing looks like it has been polished, filed, cleaned up.
Thank you. I found some threads with that. Before I go and buy anything I'll try a couple hundred rounds of high brass and see how it runs then.
